what maryland college has a branch college in New Mexico?

You’re thinking of St. John’s in Annapolis. I’m not sure why exactly you’re curious about it, so rather than give you a whole spiel you may not need, I’ll link you to their website: http://www.stjohnscollege.edu/asp/home.aspx .

I’m not sure that there is one. I know it’s not UMUC. Call U of M and find out their locations.
