Family Gem

Create your own family tree

Family Gem is an app for Android designed to manage family trees. At the moment it's completely free and open source.


With Family Gem you can:

  • Create a family tree from scratch, entering names, dates, places, various events, photos and sources.
  • Import an existing family tree through a GEDCOM file and modify it as you want.
  • Export the family tree you created (via GEDCOM again) to import in every other genealogy program.
  • Share a tree with your relatives, letting them improve it and receiving back the updates. Then you can choose whether accept them or not.

Minimum supported version is Android 4.4 KitKat (API 19), maximum is Android 12 S (API 31). The intent is that data structure respects as much as possible the latest version of GEDCOM standard: 5.5.1 and possibly also 5.5.5.
Family Gem is strongly based on the library Gedcom 5 Java by FamilySearch.


The code provided in this repository should compile and build a working version of Family Gem, but with some limitations:

Missing Limitation
App signature You loose saved trees when you install over a signed version
Server account You can't share trees
GeoNames "demo" account Place names suggestions probably don't appear

The code (classes, variables, comments...) is almost all written in Italian (my native language), because I started just as a personal hobby project. Obviously everyone expects an English code: it's hard to change at this point but I'm trying to translate all to English.


The translation of Family Gem user interface is managed on Weblate. Contribution to translation in any language is really appreciated. You need a Weblate account to freely work there, but also without account you can make suggestions to already existing translations.
