Testing worldwide I guess as I do not live in the States but an American 'cousin' [through Genforum and a common ancestor]alerted me to it. There are several companies which do the test but I like Family Tree DNA and it worked for me as I now have so many 'cousins'. I am in email contact with a couple and we are working hard on making a connection. We compared lists of matches and found 25 we shared so are now emailing those 25 to compare their lists.Each time we have a match with someone else we narrow the range and of where to look for the connection. The more people who test the more matches we are likely to have. I took the more expensive route to these cousins as I tested first for mtDNA and then upgraded to Family Finder. www.familytreedna.com I visited Romania last year by the way.
