I realize that GedMatch is a great thing ...and I understand that Ancestry doesn't have the tools to work out the DNA match but unless every one of my matches also upload to GedMatch, It (GedMatch) is not going to bring me any closer to figuring out my matches on "Ancestry".
I'm trying to find a way to make my ancestry matches have some meaning, here on Ancestry.

I know that I can't prove anything (DNA wise) by my matches here but they have provided some great clues of additional areas to look for records ... hence my trying to interpret what side of my family I should focus on when looking at my matches....
