Hannafin(sp?) and Donoghue family

I'm seeking to know whether there are any descendants of a Hannafin(sp?) family who lived in Ballymacaquim East, Killahan civil parish in and around 1912 or thereabouts. Jeremiah Hannafin married my great grandaunt Margaret Donoghue, on February 18, 1912 in the Catholic chapel at Causeway. They had two children that I know about, John and Daniel ...there may be more that I have yet to find. The two sons were born between 1912 and 1913.

I haven't as yet found anything further on any of the family but I wonder if the sons, John and Daniel might have married and remained in Ireland to raise their families. I'm also wondering what happened to Margaret and her husband. I don't believe that they emigrated. Two of Margaret's brothers including my great grandfather Jeremiah Donoghue did emigrate to Holyoke, MA.

Margaret also had a brother James who never married and two sisters who did and who all remained in Eire. The parents were James Donoghue and Honorai Long and they were originally from Dromartin.
