What names would you give these two?

I'm driving across half of Europe on my way to a new job and stopped in a town called Poitiers in France. A walk into town took me by a small paddock where these two charming creatures were calmly chewing their way through the undergrowth.

I think it may be a parent and offspring due to the differences between horns they have but have no clue of the sex of either but the shorter horned one was the more curious. Neither was especially talkative but both did make noises that drew my attention.

My guess us they're Margaret and Devin with Devin being the son of Margaret.
