Behind the Numbers:  Elizabeth Hirschman

  (Part Two of a Series)

We interviewed Rutgers marketing professor Elizabeth Caldwell Hirschman, author of several books and articles incorporating DNA in her research, to hear her personal story in our continuing series about the people behind the scenes in the field of DNA testing.

Elizabeth Hirschman with MBA students at Rutgers in December 2009.

When did you first get interested in DNA?

ECH: I got interested in DNA testing around 2000 when I discovered I was Melungeon after reading Brent Kennedy's 1994 book. Brent suggested several different ancestries that possibly contributed to the Melungeon population and I wanted to find out which of these were correct and which ones I had. I already suspected Jewish ancestry because of the naming patterns in my family over the past 300 years, as well as some of their habits --e.g., not eating pork, getting married in a home instead of a church, cleaning house on Friday afternoon, no eggs with blood spots, washing all meat, etc. We also had some genetic anomalies -- shovel teeth (sinodonty), palatal tori and large rear cranial extensions, as well as polydactylism.

Tell us more.

ECH:  Over the course of the past decade I have been found to have Native American, Spanish, Ashkenazi Jewish, African, Mediterranean and Gypsy/Northwestern India ancestry. My Dad turned out to have substantial Gypsy and African ancestry. He and I share a large cranial rear extension that I believe likely comes from the African ancestry -- the photos I have seen of the !Kung Bushmen look just like our head shapes. My Mom has Native American and/or Sino-Siberian ancestry. She also possessed the Asian teeth and palatal tori found in this group.

You've written several books and articles with Donald Yates; how did that come about?

ECH:  We shared ancestry from the Coopers, a prominent pioneer family in Daniel Boone’s time. In 2000, I wrote him out of the blue when he was a professor in Georgia and introduced myself and asked if possibly the Coopers were Jewish. We began to correspond by email. I told him I was sure one of the reasons I was working so hard to figure out the Melungeon story was because I had to figure out who I am. “Up until last year,”  I remember telling him, “I thought I was Scotch-Irish, English , white and Presbyterian.” It was a big transition to Sephardic, brown and Jewish. It turned out that we were distant cousins and had numerous links in our Melungeon ancestry.

What was a typical publication?

ECH: One article was called “Suddenly Melungeon! Reconstructing Consumer Identity Across the Color Line.” This was published by Routledge in 2007 in a handbook on consumer culture theory edited by Russell Belk.  

How did the Jewish findings play out?

ECH:  On a personal level, both Don and I, as well as his wife Teresa, returned to Judaism, he and Teresa in Savannah and I in New Jersey. On a professional level, we started the Melungeon Surname DNA Project, which focused on Scottish clan and Melungeon surnames (i.e., male or Y chromosome lines), and later included Native American mitochondrial DNA.  Initially, many people in the genetic genealogy community were frustrated that the incoming Jewish DNA results were not originating in the Middle East, as they had strongly believed and hoped, but were showing a lot of Khazar, Central Asian, Eastern European and Western European/Spanish/French input.

Can you elaborate?

ECH:  Critics were not happy that DNA was proving a wider and more inclusive picture of the Jewish people. Where Don and I have performed a service, I believe, is by just following the DNA trail and accepting new findings (e.g., the Gypsy/Roma) when they come in, instead of clinging to an a priori theory/belief/wish, for instance, the claim of a Middle Eastern origin for the majority of Jews.

What tests have you ordered from DNA Consultants?

ECH: I ordered every test as they became available over the years, first the Y chromosome and mitochondrial or male-line and female-line tests and later the autosomal or DNA fingerprint tests that analyze your total ancestry.  I helped organize the first autosomal Melungeon study by contributing samples from my mother and brother and obtaining samples from well-known Melungeons like Brent Kennedy and his brother Richard. Increasingly, our testing took on the aspect of a family group study. For instance, I was able by comparing multiple results from relatives to reconstruct my father’s ancestry quite satisfactorily, even though he died many years ago. I took the Rare Genes from History for all available family members. There is a streak of the Thuya Gene and First Peoples Gene in all of us, as well as the Sinti Gene (which is Gypsy), while my brother Dick got our father’s Khoisan Gene, which is African. Incidentally, it has the same source as the !Kung people and head shape I mentioned before.

If you had H. G. Wells' time machine where would you go?

ECH: I would love to be able to visit my ancestors and see what they looked like, where they lived, how they lived and learn how they got to Appalachia from such disparate parts of the world. I wish I could talk with them. My project now is to visit all the places they are known to have come from and see what the architecture, climate, food, and people are like. That is about as close to "meeting" them as I will be able to get. So far, I’ve traveled to Scotland, Ireland, Wales, England, Spain, Tunisia and Morocco on the trail of my Sephardic Jewish ancestors. I am trying to get to the Silk Road to see Central Asia, Turkey and Northwest India in the near future.

The dictionary defines "megapopulation" as a very large one, from the Greek suffix mega, the same element as in "megabyte." In statistics, a population is the whole field from which you choose a sample or representative segment. Thus, to test American Hispanic/Latinos you might draw a sample of 400 people from a predefined population of everyone with a Hispanic surname in a telephone book.

How reliable and valid your sample is depends on methodology. By combining populations you can study a metapopulation (all related populations, for instance North and South American Latin or Iberian populations) or megapopulation (all populations with Iberian ancestry in the world).

Going from the small to the large, we  have then:

Beyond Megapopulations (and percentage of total populations) These categories correspond roughly to what people used to think of as "race," a now-discredited notion. They are continent-specific, with African and Caucasian extended to North and South American African and European populations.

African   45     11%  

Amerind   24    6%

Austral 9    2%

Asian  67    17%

Caucasian  255    64%

Another Calculation We created these totals to see what kind of white versus non-white coverage the database has.

White  255  64%

Non-White  145   36%
