Mirabelle Ervine. I wish I could marry her, I am sorely sad that she dies. Why Bethesda? Why!?!
She has the best accent in game, and not mention she is beautiful. As far in to the sense of the word as any being can understand. I would say more, but her untimely death makes it sad to even bother.
As a female Wood Elf for my current playthrough I would've liked to marry Faendal. Two reasons are that there are very few wood elves in the game, and would've liked a male and female of all races eligible to bewed. Second reason is that he his the only friendly NPC to acknowledge that I am in fact a female wood elf. He says something along the lines of "Hello, forest sister. It is good to see a familiar face so far from home". Can't say that is the exact line, but it is something like that.
