Duty Family History
Duty Name Meaning
English: unexplained. Possibly a Americanized spelling of French Duthie or Dutey, both variants of Dutil, or a translation of French Dudevoir, which is probably a dit-name in origin, from one of the regiments that served in New France, perhaps a nickname for someone obsessed with duty.
