What genealogy program?
Gramps seems to be the only option for Linux and it’s powerful but weird. My sister took to using webtrees, a web based genealogy app. I had the hosting and installed it. I like TNG, also web based. Either one can be installed locally on a LAMP stack. Of course once you’ve built a tree in one software, swapping can be a ton of work. Upload/import a GEDCOM is easy but going from one program to another sometimes breaks some things like images no longer being connected to people or places.
“What genealogy program?”
MacKiev Family Tree Maker.
I just use it as a backup for my trees at Ancestry.com
If I lose my account or the Internet goes out, I can still access all the family tree data. Images and all.
