In the last three blogs, we have been discussing the topic of how anthropologists have used mtDNA to solve historical questions. In particular, we have been focusing on the analysis of historical figures who may have belonged to Haplogroup H, one of the largest European Haplogroups. We will wrap up our Haplogroup H series with this case about a World War II fighter ace and CIA pilot who died in combat in Vietnam.
Case #4: James “Earthquake McGoon” McGovern
Who was he?
James McGovern was a World War II fighter ace who died in a plane crash in Laos on May 6, 1954 when the Civil Air Transport plane that he was flying to provide ammunition to French troops was hit by groundfire. McGovern and Buford (an American co-pilot) and two French Corporal Chiefs were killed instantly, making McGovern and Buford the first two Americans to die in combat in Vietnam.
The source of his nickname:
At six feet and 260 pounds, McGovern was considered large for a fighter pilot, prompting his nickname “Earthquake McGoon” after the fierce and primitively charismatic (hulking hillbilly) wrestler from the popular Li’l Abner comic strip.
What were the anthropologists trying to find out? ie why was his DNA tested?
Between 1997 and 2002, multiple investigations of the site of incident were done by different teams (including joint US-Lao teams); however, only small fragments of aircraft wreckage were found, but no human burial sites were located. In 2002, while investigating an unrelated crash near the Ban Sot area, the JTF-FA team discovered an old C-119 (the type of plan that McGovern was flying) propeller. A few months later, human remains of a single individual were discovered from an unmarked grave, leading to speculation that the grave may have belonged to James McGovern.
The main purpose of the project was to determine whether the remains belonged to James McGovern.
Who’s Who in researching this project:
- Irwin et al from Armed Forces DNA Identification Laboratory, Armed Forces Institute of Pathology, Rockville, USA.
- Holland et al from Joint POW/MIA Accounting Command - Central Identification Laboratory, Hawaii, USA
Top peer reviewed research publications for genetic identification of James McGovern:
This table lists the most significant papers for the James McGovern case and the DNA tests that were performed to identify his remains in peer reviewed journals. Links are provided to access the original articles.
These papers provide the extent of what is known today about the DNA of James McGovern and provides answers to the question of whether the remains discovered in the grave belong to the James McGovern.
As further information becomes available, this table will be updated.
Solving the case: Collecting DNA samples
The first step in solving the case involved collecting DNA samples from the remains and locating living relatives of James McGovern for DNA testing.
- The remains: DNA was extracted from the left femur obtained in the excavation (putative McGovern).
- The relatives: DNA samples were collected from living relatives of James McGovern including: 1 maternal cousin (McGovern’s mother’s sister’s son), 1 sister-in-law, 4 nieces (daugthers of sister-in-law), 1 nephew (sone of sister-in-law)
The relationship of each individual tested in relation to James McGovern are shown in the pedigree below:

The DNA testing process:
Mulitple DNA testing types were performed on the remains and the relatives. To follow are the DNA test types used in this study:
- mtDNA HVR1 and mtDNA HVR2 sequencing - to confirm maternal lineage
- mtDNA SNP testing - to supplement the HVR1 and HVR2 results by improving the discrimination power of the test
- Autosomal STR testing - to confirm relationships
- Y-DNA STR testing - to confirm paternal lineage
The goal of the various test types is to firmly establish the identity of the remains by looking for proof of relationship along the maternal and paternal lines to known descendents of McGovern’s family.
Results of the DNA tests:

Summary of Results:
The results of the DNA tests were able to confirm the following:
- The mtDNA profile of the Remains was identical to the mtDNA profile of McGovern’s Maternal Cousin.
- The Y-DNA STR haplotype of the Remains was identical to the Y-DNA STR haplotype of McGvoern’s Paternal Nephew.
Based on statistical analysis of data available, the likelihood ratio that the Remains belong to a male individual who is related to McGovern’s living family members is 96,900, thus successfully establishing that the remains are indeed those of McGovern who died in 1954.
According to Dr. Thomas Holland (director of JPAC’s Central Identification Laboratory), McGovern was the second person ever identified by their laboratory through forensic analysis of Y-DNA. Most cases involving old and highly degraded samples tend to rely on mtDNA analysis since mtDNA is far more stable than Y-DNA when examining extremely old or degraded samples.
The Aftermath:
A military funeral was held in New Jersey on October 28, 2005 to honor this well-known US military pilot.
Haplogroup Analysis:
Although the original researchers did not intend to determine the haplogroup of James McGovern, amateur genetic genealogists have stated that McGovern belonged to Haplogroup H. Let’s take a look at how they have arrived at this conclusion:
Step 1: To begin, click here to download the mtDNA Haplogroup Map. You will need to use this map to follow along in this discussion.
Step 2: Identify the presence and absence of McGovern’s mtDNA markers on the map. Starting from the CRS, move outwards and cross off all markers that McGovern does not have, circle all of the markers that he does have and put a question mark next to the markers that have not been tested:

Based on the coding region results, McGovern is negative for the marker 7028, thus excluding him from all haplogroups except Haplogroup H. The absence of markers in his HVR1 (except for 16519), and the absence of coding region marker 4580 further suggests that McGovern belongs to Haplogroup H.
Can we determine his subclade?
If McGovern is truly a member of Haplogroup H, let’s see if we can find out which Subclade of H he belongs to. To proceed, click here to download and print the H Subclade map, as you will need it to follow along with this discussion.
Again, circle the markers that McGovern does have and cross out the markers that McGovern definitely does not have. In this case, we will leave all unknown markers untouched.

McGovern is positive for the coding region marker 3010, which is a defining marker for Subclade H1. However, he is negative for 477, indicating that he is not from sublineage H1c, and he is negative for 12858, indicating that he is not likely H1c2. Other coding results indicate that McGovern is negative for 5004, indicating that he is not likely H4; he is negative for 4793, indicating that he is not likley H7; and he is negative for 14470, indicating that he is not likely H10.
Based on the known DNA markers results for McGovern obtained to date, it is safe to conclude that he is very likely a member of Haplogroup H. If he is indeed a member of Haplogroup H, his most likely a descendent of Subclade is H1. However, in order to confirm his Subclade, a Subclade test would be required to examine markers 1638, 6776, 13101, 4310, 8448, 3936, 14872, 11377, 6352, 1039, 3915, 13708, 14869 and 8494 to exclude the possibility of other H Subclades, including H2, H3, H8, H9, H11, H12, H13, H14, H15, H16, H17, H18, H19, and H21. Other markers that would be useful to examine are 6365, 8271, 3796, 9066 and 9150 to determine which further sublineage of H1 he belongs to.

The mtDNA SNP Backbone Test Panel examines 20 SNP markers in the coding region of the mtDNA. These 20 SNP markers are the defining markers for determining an individual’s mtDNA haplogroup when used together with the HVR1 and HVR2 results. The chart below lists the 20 markers that are included in this panel, and the haplogroups that they define.

In the last few blogs, we have been discussing the topic of how anthropologists have used mtDNA to solve historical questions. In this blog, we will continue our analysis of historical figures who may have belonged to haplogroup H.
Case #3: Empress Alexandra Feodorovna of Russia
Who was she?
Empress Alexandra Feodorovna of Russia, the granddaughter of Queen Victoria was born on June 6, 1872 as Princess Alix of Hess and by Rhine in Darmstadt (Germany). She was the sixth child of Grand Duke Louis IV of Hesse and by Rhine and Princess Alice of the United Kingdom. She was the princess consort of Nicholas II, and the last Tsaritsa of Russia.
What were the anthropologists trying to find out? ie why was her DNA tested?
At the end of the February Revolution of 1917, Tsar Nicholas II was forced to abdicate. The Romanov family were imprisoned in Ipatiev House at Ekaterinburg in the Urals of Central Russia in 1918 with three servants and the family doctor. On the night of July 16, 1918, the entire Romanov family was shot and killed by the Bolshevik firing squad.
According to legend, two bodies were burnt and the others were buried in a roadside pit. To hinder identification, sulphuric acid was said to have been thrown into the open grave and a truck was driven back and forth over the grave.
The case remained a mystery until July 1991, when nine human skeletons were discovered in a shallow pit around 20 miles from Ekaterinburg, Russia. Historians speculated that the remains belonged to the Romanov family. To help solve the mystery, DNA testing was performed to identify the remains.

Solving the case: Collecting DNA samples from the Ekaterinburg remains
The first step in solving this case is to test the DNA of the Ekateringburg remains. After the DNA type of the remains is known, it can be compared to the DNA type of known relatives in the royal family. Since Tsarina Alexandra is the maternal granddaughter of Queen Victoria (Queen Victoria is her mother’s mother), Tsarina Alexandra must have inherited her mtDNA from Queen Victoria. A living descendent of Queen Victoria who carries Queen Victoria’s mtDNA type is Prince Philip. The following diagram shows in purple how the mtDNA is passed down from Queen Victoria to her descendents and which one of her descendents carry her mtDNA:

Individuals who inherited the mtDNA type of Queen Victoria are highlighted in purple.
The descendent tree for Queen Victoria indicates that Tsarina Alexandra should have the same mtDNA profile as Prince Philip as well as other living and deceased descendents from the same line. By collecting the DNA sample from known family members, scientists can find out the expected mtDNA type for Tsarina Alexandra and her children and use it to identify the remains.
Who was tested to solve this case?
- A blood sample was collected from Prince Philip, a living descendant of Queen Victoria (maternal grandmother of Tsarina Alexandra).
- Bone fragments from each of the nine skeletal remains found in Ekaterinburg.
Three Types of DNA tests were performed to confirm the identity of the Ekateringburg remains:
- Gender determination: To identify the gender of each of the nine skeletal remains.
- Autosomal STR testing: To determine whether the nine skeletons are related to each other, ie in the same family.
- Mitochondrial HVR1 and HVR2 sequencing: To examine whether the skeletal remains are members of the Romanov family by comparing the mtDNA profile of the remains to the mtDNA of known royal family members.
Step 1: Autosomal STR Testing: To determine whether the 9 skeletons are related to each other
Autosomal STR testing (the same technology used for paternity testing) was used to determine whether the nine skeletons are from the same family.

The results of the autosomal test confirmed the following:
- Skeletons 3, 4, 5, 6, and 7 belonged to the same family.
- Skeletons 3, 4, 5, 6 and 7 are likely a family group consisting of three children and both of their parents.
- Skeletons 1, 2, 8, 9 are not related to skeletons 3, 4, 5, 6, and 7.
This information is consistent with the skeletons belonging to members of the Romanov family.
Step 2: Determining the gender of the skeletons
The next set of tests sets out to determine the gender of the skeletons.

The results of the gender determination tests showed that four of the skeletons are male and one was female. The combined results of the autosomal test and gender test leads to the speculation that skeleton #4 is the father, skeleton #7 is the mother, and skeletons 3, 5, and 6 are their daughters.
Step 3: What if the skeletons belonged to the Romanov family?
If the remains truly belong to the Romanov family, then:
- Skeleton 4 “father” should belong to Tsar Nicholas II
- Skeleton 7 “mother” should belong to Tsarina Alexandra
- Skeletons 3, 5, and 6 are three of their 4 daughters

The next step is to confirm the speculated identities by comparing each skeleton to living royal family members.
Step 4: Solving the mystery. Confirming the identity of Skeleton #7, Tsarina Alexandra and her daughters, Skeletons 3, 5, and 6
Now that the preliminary studies indicate the possible identities of each of the skeletons, the next step is to confirm the identity by comparing to the DNA of living royal family members. Tsarina Alexandra is the grandaughter of Queen Victoria, and her mtDNA should be identical to the mtDNA of Prince Philip, a living descendent of Queen Victoria.
The next step is to test the mtDNA of Prince Philip and compare it to the mtDNA of the skeletons.

Conclusion: The results of the mtDNA test confirm the following:
- The putative Tsarina Alexandra’s mtDNA (skeleton 7) is a perfect match to the mtDNA profile of Prince Philip, indicating that it is the actual skeleton of Tsarina Alexandra.
- Tsarina Alexandra’s mtDNA is a perfect match to the mtDNA profile of Skeletons 3, 5, and 6, her putative daughters.
- Skeletons 3, 5, and 6 are also identical to Prince Philip’s mtDNA, indicating that they are the actual skeletons of Tsarina Alexandra’s daughters.
- The putative Tsar Nicholas II’s mtDNA (skeleton 4) does not match the mtDNA of Prince Philip. This is expected since Tsar Nicholas II is not a direct descendent of Queen Victoria. We will discuss the set of analysis that was conducted to confirm the identity of Tsar Nicholas II in a separate blog.
In summary, the DNA studies confirm that five out of the nine skeletons discovered truly belonged to the Romanov family, namely Tsar Nicholas II, Tsarina Alexandra, and 3 of their 4 daughters. The skeleton of one of their daughters and their only son, Alexei, remain missing.
The Aftermath: Doubts and Controversies
Since the findings, the skeletons were reburied with honors in the imperial-era capital of St. Peterburg. The two remaining children remain missing.
The scientific findings and results have since been challenged by Knight et al, suggesting irregularities and sample handling deficiencies.
Recent Findings from the summer of 2007
In the summer of 2007, using metal detectors and metal rods as probes, two burned partial skeletons were discovered at a bonfire site near Ekaterinburg, 900 miles east of Moscow. 15 intact bone fragments and more than 40 pieces of charred bone were discovered.
The site appeared to match the site described in Yurovsky’s (the Bolshevfik officer in charge of the Romanovs’ captivity) memoirs. According to his memoirs, the bodies of nine victims were doused with sulphuric acid and buried along a road. Alexei’s body and one of his sister’s bodies was burned and left in a pit nearby
Preliminary analysis of the bones showed that the remains were from a boy roughly between the ages of 10 to 13 years old at the time of death, the putative Alexei and a young woman roughly between the ages of 18 to 23 years old at the time of death, attributed to one of the Romanov daughters, likely Maria or Anastasia.
Genetic investigations were performed in the Sverdlovsk Regional Forensic Medicine Bureau, a lab in Moscow, and a US laboratory, the University of Massachusettes Medical School.
On April 30, 2008, the groups claimed that DNA testing (mainly mitochondrial DNA analysis) proved that the remains belonged to Tsarevich Alexei and one of his sisters (likely Maria) were released in several major newspapers and news sources (including New York Times, BBC, and MSNBC).
What is the haplogroup of Queen Victoria’s descendents?
Now that the mtDNA type of Queen Victoria’s line is known, amateur genealogists from around the world have used the data to compare to their own families to see if they may have links to royalty.
Although the original researchers never attempted to use the data from the study to determine the haplogroup of this royal family line, amateur genealogists have tried t use the data from the study to determine the mtDNA haplogroup of Queen Victoria’s line, concluding that Queen Victoria and her descendent Tsarina Alexandra belonged to Haplogroup H. Let’s take a look at the raw data and see how accurate they are.
Step 1: Click here to download and print the mtDNA Haplogroup map so that you can follow along with the discussion.
Step 2: Identify the presence and absence of HVR1 markers on the map.
Tsarina Alexandra only had two HVR1 markers, namely 16111 and 16357. On the map, all HVR1 markers are in blue. Starting from the CRS, move outwards and cross off all of the HVR1 markers that Tsarina Alexandra does not have, circle the ones that she does have and put a question mark next to the ones that are unknown:

The results of the HVR1 test helps to eliminate the haplogroups that Tsarina Alexandra definitely does not belong to, and shows that Tsarina Alexandra must belong to either Haplogroup R, Pre-HV, HV, H, or the CRS branch of H.
Step 3: Identify the presence or absence of HVR2 markers on the map:
Tsarina Alexandra has 2 markers in her HVR2 region, namely 263 and 315.1. On the map, all HVR2 markers are red. Starting from the CRS, move outwards and cross off all of the HVR2 markers that Tsarina Alexandra does not have and circle all of the HVR2 markers that she does have:

The results of the HVR2 test helps to eliminate Haplogroup R and shows that Tsarina Alexandra must belong to either Haplogroup Pre-HV, HV, or H. Tsarina Alexandra has marker 263 which brings her away from CRS, indicating that she is unlikely to belong to CRS, but the presence of 263 cannot eliminate her from CRS as such a conclusion woudl require more data from the coding region.
In conclusion, the results of the scientific studies show that Tsarina Alexandra can belong to any one of the following Haplogroups:
These results are similar to those of Marie Antoinette, even though the exact mtDNA mutations that they carry are slightly different. To confirm whether Tsarina Alexandra is really a member of Haplogroup H, one would need to test the coding region of her mtDNA to confirm that she does not have markers 7028 and 14766. However, no coding region data was ever available for Tsarina Alexandra or for any of her living or deceased relatives, so there is no way to confirm that she is a member of Haplogroup H. Since the original researchers were aiming to identify her remains rather than to determine her haplogroup, the coding region was never examined and in this particular case, coding region SNP test is required to confirm her haplogroup.
In conclusion, it is pre-mature to conclude that Tsarina Alexandra is a member of Haplogroup H, but the data from the studies to date do serve to narrow down her possible haplogroups to H, HV, and Pre-HV. Further studies woud need to focus on markers 7028 and 14766 in the coding region which would provide a determination of which Haplogroup Tsarina Alexandra actually belongs to, and if she does in fact belong to Haplogroup H, further H subclade testing using the H subclade test panel should confirm which branch of H she falls into.
