Galway, where they generally anglicise the name Mahon; (see Ó Macháin); and (2) of an ecclesiastical family—a branch of the Ui Fiachrach— in Co. Sligo, who were erenaghs of Killaraght, in the barony of Coolavin, and keepers of the cross of St. Attracta. They were great patrons of learning. Many of them were distinguished ecclesiastics. Gregory O Mochain was Archbishop of Tuam in the early part of the 14th century. Ó Mocháin is now a fairly common surname all through the South of Ireland, as well as in Connacht. In Munster, it is generally anglicised Vaughan, a form evidently derived from the genitive case Uí Mhocháin. Compare with the old anglicised form Voghane.
