I mean it may seem weird as it is though Azura is most likely the one he married. They both seek peace in a world of loss. They are also to closest to each other. If you read the all their conversations they say that the feel ease with one another, like who wouldn't wanna marry your best friend? Even tho its probably no a good idea for a lot people. They may be cousins but the time period is like a medieval magical age. Which back then a lot of when things happened. So Azure is the most "canon" wife you can get.
