For both men and women.

In general, last names, ending with "a" is pretty difficult case.

If before "a" there is vowel (mostly у or и), then you do not decline them. For example, Галуа, Моруа, Делакруа, Моравиа, Эриа, Эредиа, Гулиа.

For all the last names ending with non-stressed vowel, which goes after consonant - use first declension.

For example, Рибера — Риберы, Рибере, Риберу, Риберой, Сенека — Сенеки и т.д.;

Also Кафка, Спиноза, Сметана, Петрарка, Куросава, Глинка, Дейнека, Гулыга, Олеша, Нагнибеда, Окуджава.

If ending "a" is stressed and goes after consonant, there are 2 variants:

1) Non-declinable last names of French origin: Дюма, Тома, Дега, Люка, Ферма, Гамарра, Петипа и др.

2) Last name of other origin (Slavic, Middle Eastern, etc...) - use first declension. For example: Митта, Сковорода, Кочерга, Кваша, Цадаса, Хамза и др.

It's interesting that his family name is in the form of a female patronymic from the masculine name for a coachman. I'd like to also know the history of that.
