I have a practical question that is easy to ask, but not obvious to me how to achieve. Gedmatch has a limitation of 10,000 people for gedcom uploads. My primary database is a single tree with about 22,000 people. (maybe 5% of this is ancestors, the remainder descendants iof ancestors).
Is there a practical way to create a separate paternal and maternal tree, or even paternal grandfather, grandmother, and maternal grandfather grandmother tree?
