thank you for your contribution on translate Family Gem!
You are right. All the titles of person and family facts are not translated.
It's because they come from the Gedcom library by FamilySearch, where they are hard-coded in English.
At the moment no translation system is provided by FamilySearch.
And thank you for writing me in Italian!
But I think it's better to keep this group comprehensible for readers of all the world.
