This question might have already been asked but I can't find it so here it is:
I have two (fictional) listed family trees with multiple families (since I couldn't figure out how to do this exact thing). It was fine until two people from either tree are now getting married and I can't use the "partner already in tree" function. Like I said, the families are huge and I don't feel like re entering ALL those people again. Is there a way to link the trees together by marriage without redoing all that work?
