there is a slight problem with Surnames in Slavic languages (Czech f.e.). Our family names have different form for different genders. Ie.:
Generally suffix -ová is added at the end of the name:
Novák / Nováková
Klaus / Klausová
But there are exception such as:
Only last letter changes:
Surý / Surá
or no change at all:
Krejčí / Krejčí
Ovčaří / Ovčaří
So it would be great if one can set female form of the surname in the family settings. This is important for presentation and for genealogic research as well.
