Cahill
Cahill is a name of Irish origin. It is the anglicised version of the Gaelic "Ó Cathail" meaning "descendant of Cathal".
"Cathal" consists of two parts: "cath" means battle; the second could be "val", so that the name as a whole meant "battle ruler" or "strong in battle", or it could be "all", so that the name as a whole meant "great warrior".
