I assume the bottom line is trying to find out who your grand father was. In looking at your profile, it seems to me that if you are looking for one of your grandfathers, Autosomal DNA (AuDNA) would be the way to go. You don't have an AuDNA test listed in Wikitree. While it's not guaranteed, I would think you should be able to find some first or second cousins this way through GEDmatch or perhaps even on Wikitree. As was stated earlier, all you do on Wikitree is add the details of the test (the fact of), and not the raw data from the test itself. Happy Hunting!
