Efedy History, Family Crest & Coats of Arms

The surname Efedy originally appeared in Gaelic as "Mac an Mhadaidh," which is probably derived from the word "madadh," which means "warrior, dog." [1]

Another source claims the family claim descent through Owen Buac, brother of Owen Fionn, ancestor of O'Madadhain, of Connaught, slain, 1008; Anglicized O'Madden, Madden. The Madden family of Longford, County Galway, the O'Madden family of Balbriggan, County Dublin and the Madden family of Ulster are all branches of the original. [2]

Alternatively, the name could have been from "descendant of little Matthew (gift of Jehovah.)" [3]

Early Origins of the Efedy family

The surname Efedy was first found in County Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, where they held a family seat from ancient times.

We did find this interesting entry for the Mudrigan variant in the parish of St. Martin, Cornwall, England: "Although this parish contains no manor, Mudgian is said formerly to have had manorial rights, when it belonged to a family of this name, and was their seat. From the Mudgians it passed with an heiress in marriage to the Chynoweths." [4]
