Thanks for your email. I will have to do a bit of research to reply properly to your enquiry. I am going to give you a little bit of family tree on the Horan side which I built up with the help of my parents and other people who have been very helpful, particularily a Michael Gleeson, Clogher, near Thurles and John Kelly, Hillview, Chadville, Cappawhite, Co. Tipperary. Both are excellent on family histories.
My great grandfather was Conor Horan,Torah, Rossmore. Born 1813,died 1895. He married Margaret Ryan, from near Drombane. One of their sons, John Horan ,born 1860,died 1932,
married Johanna Quirke,Sollogheadbeg,Donohill. Johanna, was born 1867, died 1950. Her son, Con Horan, born 1914, is my father. He had a brother, Tom Horan,who married Kathy O Gorman. My dad married, Nora Barry, (R.I.P.)Clougherviller, Herbertstown, Co. Limerick. This for a beginning will give you a start. Best of luck
with your research.
