I'm Chris's brother. I quite like the link between Hobro, a town in Denmark, and Hobroughs in England for derivation of the name. I wonder if there is a link betweeen Hoppach and Hobro. I'm really only interested in the name itself and the origin and that is beginning to be something of a lost cause I think. Ho is the name of the fiord, bro means bridge. And it seems a long bow to draw to link that all up with your own surname of course.
