There are five types of elves in Skyrim:
1. High Elf (Altmer)
2. Dark Elf (Dunmer)
3. Wood Elf (Bosmer)
4. Snow Elf (Falmer)
5. Orcs (Orsimer).
All five races descend from the Aldmer, the original elvish race, there are a few other subtypes such as the Chimer, and more importantly, the Dwemer, but they do not appear in person.

Your race has no part in getting married, I don't think there is any wood elf partners to marry though, so you may have to settle for another race you want to marry.
