Comments for the name Arnborg

This is the name of a very small town near my city in Denmark. At first I thought that was odd, since it's a Swedish name, or more place name, but then again part of Sweden have been in Danish possesion at one point.

I'm not familiar with this as a Swedish name, however there is the name Ambjörn, old spelling Arnbiorn, a combination of the words for eagle and bear.
