I found a Michael Colleary, of Ranaghan, Co. Sligo married to Margaret Fahy of Thornhill, Co. Sligo on 20 Feb. 1860 (incidentally 100 years to the day before my parents were married!) in the parish of Ballysadare & Kilvarnet. Groom's father was Daniel Colleary, mother Margaret Connell. Bride's father was Patrick Fahy, mother Brigid Kane. Both Ranaghan and Thornhill are near Ballinacarrow, Co. Sligo.
