O'Neall

O'Neall is a surname of Irish origin. It is a variant spelling of the more common surname O'Neill, itself derived from the Gaelic "Ó Néill," meaning "descendant of Niall." Niall, in this context, most likely refers to Niall Noígíallach (Niall of the Nine Hostages), a legendary High King of Ireland believed to have lived in the 4th or 5th century AD. The O'Neills were a powerful Gaelic dynasty based in Ulster, holding significant influence for centuries. The variation in spelling to O'Neall, while less frequent, is found in historical records and among families who emigrated from Ireland. The surname carries with it a legacy of Irish history, lineage, and association with a prominent clan.
