There are a few families of O'Connors in the Castlegregory parish area. My mother is one of them. Her family originated from Faha, Cloghane. Other O'Connor families were in Kilcummin, Aughacasla, Maharees. I can't think of any others at the moment. The Maharees O'Connors are connected to ours through marriage. My grand-aunt was married to one of the Maharees O'Connors.
