Padraig Mac Giolla-Domhnaigh

Bird—The names Heany, in North Connacht; Henaghan and Henahan, in South Mayo and districts surrounding Tuam, Co. Galway; and McEneany. McEneney, and McNeney, in South Monaghan, Louth, and Meath, have been anglicised Bird, presumably because the word "can" (bird) enters into the construction of the names. The Gaelic of the surnames are respectively O h-Eanaigh, O h-Eanacháin, and Mac An-Eanaigh.
