"Blend of Betty and Ann"
The name Bettyann is commonly a female name from the "English" origin.
Bettyann is a compound given name made from Betty and Ann, written as a single word. Betty is an English pet form of Elizabeth, and Ann is the English form of Anna, which derives from the Hebrew Hannah. Both elements were long established on their own before the combined form appears in United States birth records in 1917.
The pronunciation of Bettyann is BET-ee-an.
