Recorded as Hannan, Hannon, Honnan and possibly others, this is a Gaelic surname which can be Scottish or Irish. It originates from the early clan name O' Hannain, meaning the male descendant of Annan, and originally the surname was associated with Counties Limerick, Galway and Roscommon. The first recording of the name dates back to the mid 13th Century (see below). The surname is often confused and particularly in Scotland with the surnames Hanna and Hannay, although these are thought to be from a completely different source. Early examples of recordings include Michael, son of John and Ellen Hannon, who was christened on October 19th 1795, at Mitchelstown, County Cork, Ireland whilst Patrick Hannan (1842 - 1925), who was born in County Clare, discovered the Kalgoorlie goldfield in Western Australia...
