The name Dunford can be traced back to Yorkshire, England. It's a place name too, where there was a ford on a river, the name of which escapes me. Dun also means brown (as in 'Old Dun Cow', which caught fire in the song), so it could be brown ford, or muddy ford. It's not all that common over here (except in Abbotsbury, Dorset, where in 1940, there were 32 children in the school with that surname, all traceable back to one family who moved there in 1814....).

Thanks for looking though.
