[My Little Pony: Friendship is Magic] How do names work?

How do names work in this world?  Does a pony take a name of their spouse when they get married, or do the Cake and Pie parents just coincidentally happen to have similar names?  What happens when your name and cutie mark contradict? Such as, what if your pony parents named you Cuddle Bunny and yet your talent and cutie mark have to do with fighting? Do ponies ever change their names based on their cutie mark?

I sort of assume it's simply like real life- that is, you are given a name at birth, and then you can change it at a later point if you want. Apparently, lots of people change their names to suit their cutie marks, but not all do.   


I don't think there's much more of a complex rule here then "pony culture is more accepting of name changing then ours", maybe.
