[hrothgars]

I have an extremely common Welsh/English surname. Tracing my ancestry far enough back, the paternal line of my family hails from Denmark, and the Scandinavian derivation of my surname is Hrothgarsson, "son of Hrothgar."

tl;dr - "Rogers" is the anglo-bastardization of the Olde English "Hrothgars," which itself is an abbreviation of the Germanic "Hrothgarsson."

I most frequently see folks misspell or switch it with "Hogarth," the kid from The Iron Giant.
