What does the baby name “Oshea” mean?

Origin of the baby name Oshea

Oshea is an anglicised form of the Irish surname O'Shea, from the Gaelic "Ó Séaghdha," meaning "descendant of Séaghdha." The personal name Séaghdha is believed to mean "hawk-like," "majestic," or "fine," evoking the nobility and keen-sightedness of a bird of prey. The "O'" prefix indicating descent from a named ancestor was one of the great markers of Irish Gaelic naming culture, and Oshea carries that heritage directly.
