O'Finnan History, Family Crest & Coats of Arms
The roots of the O'Finnan surname in Ireland are somewhat unclear; it seems that the name was both native Irish Gaelic, and Norman. The Gaelic name "ó Fionnáin" seems to be derived from Gaelic word "fionn, "which means "fair." This Gaelic name has been Anglicized as Finan and Fanning, both of which are also Norman names that came to Ireland in the 12th century.
Early Origins of the O'Finnan family
The surname O'Finnan was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they were of the Hy Fiachrach Sept. One notable bearer of the personal name who lived several centuries prior to the introduction of hereditary surnames was St. Finan (Finan of Lindisfarne) who died in 661 AD, and achieved repute for his missionary work in England. He was Bishop of Lindisfarne (651-661) and he converted the kings Sigebert of Essex and Peada of the Middle Angles to Christianity.
