McManus

About

McManus is an Irish surname. It is derived from the Irish Gaelic "Mac Mághnais", in modern Irish "McMaghnuis" which means "Son of Magnus". Its earlier origin is from the Latin "magnus", meaning "great". The Normans used it to honour Charlemange (742–814), as Carolus Magnus. Variant spellings of the name include MacManus, Manus and MacManners. The English form, Moyne, is also found in Ulster. In Scotland it is a sept of Clan Colquhoun.
