[Surname] Dunham
I think this is Scottish or English. "Dun" is likely "dark" or "fort" but I can't find anything for the "ham" part.

The placename Dunham is from dun 'hill' and ham 'homestead'.
English, from one or more locations of the name; Norfolk, Nottinghamshire, Cheshire. The last of these is called Dunham-on-the-Hill.
I agree with M. Lepic on the meaning.
