Freud

Freud is sort of a brand name in itself. I never thought much about what it means until I saw it in Hank's and Hodge's book. It comes from German "freud" which means joy and it was originally given as nickname for a cheerful person. I do not know if Freud was that cheerful, but one of his ancestors ought to have been.
The name seems to exist in various other Northern European nations. In Dutch, it is Vreugde and in Swedish Fröjd.
