RE: FamilyTreeDNA test & questions by Greg Limpet

Greg,

FamilyTreeDNA is the BEST company doing DNA testing in the world today. It was the first consumer DNA company to offer genealogical DNA testing, specifically focusing on Y-DNA and mtDNA tests to help individuals trace their ancestry. I've been using their tests in my genealogy research for 20 years.

There's more than one type of DNA test -- which one did you take?

Autosomal DNA ("Family Finder" on FTDNA) tests both your father's and mother's sides of your family. All the ancestors' surnames and DNA lines are in the match results, like a huge melting pot. That's the most popular test.

FTDNA allows you to transfer your autosomal test results from other companies. As their web site says: "Already tested with AncestryDNA, 23andMe, or MyHeritage? Upload your raw DNA data to FamilyTreeDNA and discover even more relatives."

Y-DNA tests ONLY the paternal side of your family: father > son > grandson > great-grandson, and so on. ONE surname in a straight ancestral line, a test for males only. For instance, I can't take a Y-DNA test to check my Crenshaw ancestry; I had my brother, Richard Crenshaw, take the Y-DNA test. The DNA line goes from him to our father, Crenshaw grandfather, Crenshaw great-grandfather, etc.

FTDNA is the only company doing Y-DNA testing. The DNA tests with all the other companies: Ancestry.com, MyHeritage, 23&Me, etc., are ONLY and ALL autosomal.

mtDNA tests ONLY the maternal side of your family: mother > daughter > granddaughter, and so on. My mtDNA test results trace from me to my mother, to her mother, to her mother's mother, and so on.

Ancestry has the largest DNA client database, and taking their test probably WOULD be helpful. You'd be reaching the largest number of possible matches, on all sides of your family. And I'd certainly recommend joining the North of Ireland DNA project managed by NIFHS, as described by Elwyn Soutter. It's a great project.

Good luck with DNA and with your ongoing ancestor search,

Annie
