I have tested with both Ancestry DNA and FTDNA. I have good reasons for both. My ethnicity conclusions were very close on the two results. But Ancestry has provided the majority of my matches. I have actually proved several lines through the use of Ancestry. I had a couple lines where I likely had two or three women cousins of about the same names who might be my ancestor. When I got possible matches up the tree I was able to conclude I had chosen the correct woman to be my direct ancestor. Or it could have gone the other way, and I would be able to rule one or more out. It does not hurt to test with all three of the major choices, but if one has a decent paper trail to submit with the DNA, one will likely get many more obvious matches with Ancestry. I solved a French Canadian line that I had looked for for some 20 years, with the DNA results and the fluke of finding a 3rd marriage record on Ancestry. With FTDNA I have received inquiries from people around the world, but without paper trails one is not likely to find matches at the 4th or 5th cousin level. Margaret Scheffler
