O'Hora (Hora) family from Ballinsleva

Discovered from existing relatives that my family lived and farmed in Ballinsleva, worshipped at Knockmore and went to school in Lisaniska. Cannot identify graves of  Gt GT Gt Grandfather Patt O'Hora Snr, died around 1864, wife Bridget Mangan, son John, Son Edward, son Thomas, who all stayed and died in area. My Gt Gt Grandfather, Patt, Jnr 1838 -1903, emigrated to Lancashire, England in 1860s and lived, raised his family and died there. Have visited Ballynahaglish graveyard but no trace there, a first cousin is there, Mary Gaughan, nee O'Hora,  cannot find them  from records in Cloghers. Any thoughts on other likely local graveyards?

Any information on this family gratefully received.
