Gramps does looks as if it's going to eventually exceed FTM, realizing the folks at FTM have access to the Gramps source code as well so maybe not.
Put a 'family fun fact' that I'm interested in is which is these is considered the 'closer related relative':
1st Cousin 6x removed
or
3rd Cousin 4x removed
or
4th Cousin 3x removed (or is there even such a thing as a 4th cousin? I've never heard that term)
Thanks.
