MERRIGAN Family History

There is some considerable doubt as to the origination of this surname. It seems to be native Irish and according to the famous Victorian Irish etymologist Father Wolfe, descends from the old Gaelic pre 10th century O'Muireagain, which would suggest that if he is correct, that the meaning is 'The son of the descendant of Mary'. This is probably a reference to a follower of the Virgin Mary, whose popularity reached a peak between the 12th and 15th centuries, although it has scarcely diminished in Ireland today.
