Billie Family History

Native American (Navajo): apparently from an American English spelling of Navajo bilį́į́ ‘his horse’ originally part of the personal names such as Bilį́į́’ Dilwo’ii ‘His Fast Horse’ (see Fasthorse). Alternatively, this surname could be from the English personal name Billy (see 2 below). Compare Billey 5 and Billy 5.

Native American (e.g. Seminole): adoption of a variant of the English personal name Billy (pet form of William) as a surname. Compare Billey 6 and Billy 6.

Americanized form of Czech and Slovak Bílý Bilý Bíly (see Bily) or Billý (see Billy) Ukrainian and Rusyn Bily. Compare Billey.

Probably also an altered form of English Billy.
