DNA for Genealogy Research

About ten years ago I persuaded my dad to have his DNA tested. We used Family Tree DNA, which was the best-known company available for genealogy DNA at that time, and which continues to be prominent in the field. Being an adventurous sort of guy, Dad went ahead and got the maximum number of markers tested for both his Y-DNA and mtDNA offered then. It was early days for that kind of thing, and the results were a bit disconcerting for my dad, so he didn’t pursue it. Basically, he didn’t match anyone with his surname at that time, and even falls into a different haplogroup than most of the participants in our one-name study. Now, 10 years later, many more people have been tested and there are some closer matches, but he has lost interest. I’m not sure I can get him to even update his account so we can follow up. It may be necessary to get my brother to have a test if we are going to learn any more.

Now, however, I’ve been given a DNA kit from 23 and Me by one of my sons, so we will have another go at it. Of course, since I’m female I don’t have any Y-DNA to test, but I’m eager to see the information about my mtDNA. My maternal line peters out in terms of genealogical knowledge with my great-great-great grandmother, who immigrated from somewhere in the British Isles in the early 1800s. Since she answered the “place of birth” question differently on several different censuses, exactly where she came from has been a mystery. While it may not be possible to determine that exactly, I hope to at least get some clue about her ethnicity; was she Irish, Anglo-Saxon, Scottish, or Welsh? Viking, Norman or Huguenot? Or maybe something else? And what does that mean, anyway? Her maiden name was Starling, and she said at various times that she was from Ireland or England, so it could be any of those. Great Britian is such a hodge-podge of people from everywhere, it may require DNA testing to determine one’s deep origins, after all.

Where to get DNA tests

If you are interested in obtaining a DNA testing kit, refer to the list of companies offering them for genealogical purposes on our wiki.

What is Y-DNA or mtDNA?

At this point, it may be a good idea to review exactly what the terms Y-DNA and mtDNA refer to. If you already know this, just skip ahead, but for those who aren’t sure, here’s a brief explanation. Essentially, Y-DNA is that passed down from father to son, while mtDNA is passed from mother to daughter. So, while we have many possible admixtures of chromosomes from all our ancestors, it is easiest to trace those on our direct paternal or maternal lines.

What DNA test results can tell us is another question. We can use them to determine whether we are closely related to someone else, or as implied earlier, to find out where our ancestors came from in the world, or their ethnicities. DNA obviously determines some of our personal traits, such as eye and skin color, and even potential temperament and intelligence (whatever those are). In some cases DNA tests can be used for medical diagnostic purposes, too, but that is outside the scope of this website. In general, if you plan to have your DNA tested, first determine what questions you want to have answered, and find a testing company who offer analysis that might provide the insights you seek. They are all slightly different in that regard, but examining their websites (listed in our wiki) should let you know what each outfit emphasizes.

I’ll be writing more about this topic when I get my own test results. Have you had your DNA tested? Were the results what you expected? Let us know your experiences in the comments.
