My male Nord wanted to marry Olfina, even had a really intricate story planned out. But, alas, it was not possible, and I'm not going to try and change it. He will live the rest of his days as a bachelor, sighing after his lost love.
My current character, female Breton warrior, is going to marry Vilkas. I have a really nice story for them.
My Bosmer female (that somehow ended up as doing magic too) married Marcurio. Now they can play "The lusty Archmage and the naughty apprentice Wizard"

Hroki - http://www.uesp.net/wiki/Skyrim:Hroki: I had to use console commands to make her a marriage option. She's a cleaner in the Inn in Markarth. I now have her living in Solitude.
I also made it so she can be a follower and boosted her archery and light armour skills to 50 so that she is usefu.....l and she looks great wearing the Triss armour

Edit: Oh yeah and I also modified her so that she is a redhead
How did you change the hair color,please?
