I am getting frustrated! Out of the hundreds and hundreds of matches, I have only found ONE relative. This is between Ancestry, and GEDmatch.
The test is my father-in-law's. He is Ukrainian/Polish, and most of the matches are coming back as people form Britain. About 90% of people I contact say they are from Britain. His side of the tree has been researched back to the 1700s, so I know for certain there is no recent British link.
Did something go wrong with my results? Is it possible to have so many "matches" but no concrete connections?
