Having just decided to use Gramps as our main genealogy application, I am wanting to move forward by enlarging our already substantial (13,378 person) database. In the process, I've created GEDCOMs, or had family members creat their own descendant GEDCOMs, for appending or merging into this still growing family tree.
My question is simple: How do I append/merge these other GEDCOM files?
Some contain previously unentered pedigree information and most are just descendant info. 
Thank you. I look forward to learning more about this excellent program!
