Effedy History, Family Crest & Coats of Arms
- Origins Available:
The surname Effedy originally appeared in Gaelic as "Mac an Mhadaidh," which is probably derived from the word "madadh," which means "warrior, dog." 
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. 
Alternatively, the name could have been from "descendant of little Matthew (gift of Jehovah.)" 
Early Origins of the Effedy family
The surname Effedy 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."
