French is an anglicised version of Defreine which has a Norman Irish origin.
The DeFreines, the ffrenches, and the Frenches, who were of noble blood, came to Ireland with Strongbow during the Norman invasion of Ireland from 1169 to 1172 AD. There were and still are two or three families of Irish peers who carry the names DeFréine, ffrench, and French. As Anglo-Normans the French family became one of the 14 Tribes of Galway, helping to found the town in 1425 AD, fortifying it to keep the locals out.
