LIDDY Family History
Recorded as Laddie, Leddie, Leddy, Liddy, Luddy, and originally O' Liddy, this is an ancient Irish surname. It originates from the Gaelic name O' Lideadha meaning "The male descendant of Lideadh", a personal name of uncertain origin, but possibly a derivative of 'leadbhd', meaning a pelt or skin. The surname is mainly associated with County Cavan, and dates back to at least the 11th century, (see below), making it one of the earliest surnames recorded anywhere in the world. Early examples of recordings taken from surviving charters, rolls and registers include Gillecrist and Malaghlyn O' Liddy of Limerick, in the year 1314, who were fined for committing some felony, whilst John O' Laidigh was the bishop of Killala in circa 1560.
