What Does the Name Gilligan Mean?
Gilligan is an Irish surname meaning "son of the little servant," from the Gaelic personal name Giollagán. Giollagán is a diminutive of giolla, an Old Irish word usually translated "servant," "follower," or "devotee"; the diminutive ending -agán gives the sense "little servant." The surname is a patronymic: Mac Giollagáin means "son of Giollagán," and Ó Giollagáin means "descendant of Giollagán."
The giolla element appears in many Irish personal names as "servant" or "devotee" of a saint, as in Giolla Brighde, "servant of Brigid." In Giollagán, however, it stands as an independent personal name with a diminutive suffix. The English spelling Gilligan represents the sound of the Gaelic name rather than translating its parts.
Gilligan Name History & Origins
Gilligan is a patronymic surname of the kind that became hereditary in Gaelic Ireland. Mac Giollagáin and Ó Giollagáin identified a person as the son or descendant of a man called Giollagán; as surnames became fixed, the form passed down within families instead of changing with each generation.
When Gaelic names were written in English from the later Middle Ages onward, scribes and officials represented the sounds with English letters. The initial G was kept, the final syllable was written -an, and the prefixes Mac and Ó were frequently dropped. Gilligan is the usual English form; Gillegan and Gillighan are closely related spellings.
As a first name, Gilligan is a transferred use of the surname. In modern popular culture it is familiar as the surname of the title character in the American television comedy Gilligan's Island (1964 - 67), a fictional use unrelated to the name's Gaelic origin.
