Variant of McGonigle.
McGonigle is an anglicized form of Gaelic 'Mac Conghail' (sometimes Mac Conghaile), a patronymic from the personal name 'Conghal', composed of ancient Celtic elements meaning ‘hound’ + ‘valor’.
The name is probably most well-known from Harry Potter, where there is a witch, and Hogwarts professor, named Minerva McGonagall.
