Encoding Surnames with Gender Variations (Greek, Czech, Russian, etc) in Gramps?

Question

Background:

In some cultures, such as Greek, Bulgarian, Russian, Slovak, Czech, etc. surnames change form depending on the gender of the bearer. For example, ...in Slovakia and Czech Republic alike, if a man is called Novák, the wife adds a feminine suffix "-ová" to his surname after the marriage, hence Nováková. The same is true for daughters which almost always inherit the father's surname with the feminine suffix. (wikipedia)

Task

For simplicity's sake, let's say that for filtering, statistical, and similar purposes, I need some surnames to be treated as equivalent.

Novák = Nováková Obama = Obamová ...

This does not qualify as a 2nd surname, but like a variable prefix - but it cannot be done automatically either, as there are exceptions to the gender morphing.

I'm using Gramps, but interested in how this is handles in general.

Answer 1

Each name in Gramps can have an associated "Group as name", "Sort as name", and "Display as name" when listing, sorting, and displaying, respectively. However, I don't think any of those are used for filtering on surname.

Answer 2

In my family database, many surnames have variant spellings. I use metaphone (which strips vowels and substitutes some consonants) to group related surnames. I had to create a custom-field for this, but some programs may be able to generate it automatically.

(Caveat: this works for filtering and statistics, but not if you wanted some way to generate the appropriate ending in report sentences).
