Databases for DNA Comparison
Posted: Mon Jan 06, 2014 12:55 pm
I recently had a relative provide a DNA sample for one of the major testing programs. He is the g-g grandson and in a direct line of males to the immigrant who came from Clare around 1850. The purpose in doing this testing was to hopefully find a connection from a very distant relative who might be able to help fill in more of the family history. (On my father's side, a cousin has done the same thing and we're hoping to find distant relatives in Germany.)
What I've come to understand is the companies that do this testing maintain their own databases and that cross-sharing is something they don't do. They can tell if there are matches within their own databases but not others. In my case, there was no match or anything close. To compare to other databases, I have to enter all the pertinent results into them individually. I have tried two others, again with no matches.
I'd like to find out if anyone knows of other companies that are doing this for other parts of the world, and especially, that might have participants from Ireland. That would increase the chances to find someone on a different family branch, one or more generations before my Irish relative. If I have my family history correct, three brothers left England, two going to Ireland and one going to Australia. One of those brothers likely stayed in Ireland...this would be the branch that I'd like to tap into.
Thanks for any help you might have.
