The word today refers to the birds' genus including ravens and crows, among others.
As a given name, its most common variations are Corvan, Korvin, Korwin, and their English equivalent Raven.
In Ireland, the surname Corvin, also transcribed as Corvan, Corravan, and others, is a corruption of the Irish (Gaelic) name O Corra Ban, part of the O Corra (in English Corr) sept or sub-clan.
The Corr sept fell under the authority of the O Neill clan.
The O Corra Bans were concentrated in County Armagh where versions of the name are still most commonly found.
