History & Origin

Hennessy anglicizes Ó hAonghusa, 'descendant of Aonghus' — the Irish god of youth and love, his name read as 'one strength' or 'one choice'. The cognac dynasty founded by an Irish émigré made the surname a luxury byword, and hip-hop made it a culture-name; both fed its use as a girls' first name.

It registers thinly and recently for girls. Rare, festive, and surname-bold — Henny waits as the nickname.

Did you know? Hennessy cognac was founded in 1765 by Richard Hennessy, an Irish soldier in French service — the bottle's Irish surname conquered France before it conquered hip-hop.
