Round, plump, bald?

Since Daddy died, Kristin and Kirstin have been burning up the internet researching the family tree. They seem to be having fun -- and the occasional difference of opinion -- and I am observing with interest. At the moment, Kristin and I are working on the origin of the surname, something I looked into a few decades back. Some of the possible orgins are boringly probable -- derivation from Roger (or Roderick) which became Dodger, became Dodge, became Dodd. Others are more entertaining. My favorite is this gem, found on a number of sites about the coat of arms:

This name is of Anglo-Saxon origin, and is one of the earliest surnames recorded. The name derives from a Germanic word used to describe something round and plump, used in Olde English pre 7th Century as a byname or nickname for such a person, and also found recorded as a personal name. The surname Dodd and Dod, and the patronymic forms Dods and Dodds, "son of Dod(d)", may mean "the hairless or close-cropped one", from the Olde English "dod", to make bare, but in the majority of cases the surname is from the medieval personal name.[This means the dude -- er, Dodd -- was bald.]
