History & Origin

Billijo is a compound of Billie, a pet form of Wilhelmina or a feminine of William, and Jo, short for Josephine or Joan. It appears in American records around mid-century, part of the fashion for Jo- paired double names, especially in the South.

It was always rare, given to only about sixteen girls a year even at its peak in the nineteen-seventies. A girl named Billijo then would be in her fifties today.

Did you know? Billijo belongs to the double first-name tradition, strong in the American South, that gave us Billie Jo, Bobbie Jo and Betty Lou, often written as two words but sometimes joined.
