Costello Genealogy & History
Costello genealogy shows that this surname originated in Ireland before 1000, starting with Gilbert de Nangle. "Nangle" or "de Anglos" meant "of England". Gilbert's son was called Mac Oisdealbhaigh, which means "son of Oisdealbhach", which translates to "resembling a deer". Costello is the anglicized version. The first mention of the family is of Gilbert de Nangle in The Four Masters in 1193. The Costello family motto is "ne te quaesiveris extra," Latin for "seek nothing beyond your sphere." Costello family history includes members with names spelled Costelloe and Costellow. Famous Costellos include singer Elvis Costello and comic Lou Costello, whose birth name was actually Louis Francis Cristillo.
