Did Hannah ever go to Montana?

Well, I doubt she would take his name, but I also wouldn't want Ron to take her name. Anyways, maybe they became companions of the Doctor's and they traveled the universe in the Tardis.

WHAT IF THEY WERE AMY AND RORY.

I was just thinking that. But Rory has light brown hair and not blonde hair, so that's a bust. But Amy does have red hair like Kim.
