In Belgium, it was common for people to use variants of given names in different contexts; the family name usually stayed the same. Namely, Dutch, French and Latin variants were used. For example, I have a relative who is referred to as Pieter (Dutch), Pierre (French), and Petrus (Latin). How do I enter this in Gramps?
You can do this with Alternative Names (in the “Names” tab of the Person Editor dialog) using either the Nickname field or Given name variant.
Its a bit inefficient and denormalized. You stored a lot of extra data for just another nickname. (This is also an issue for Russian given names that have many diminutives and variants.) A simple way to have multiple variants (possibly with an etymological and date range attributes) would be desirable.
