Patrick's death was registered in Athlone district. There are two possible Catherine Geoghegan deaths in the civil index, 1815-69 and 1828-1900. Your Catherine more likely the latter if she had a child in 1861. Carrownadurly townland is in Taghboy civil parish, part of Athlone (St. Peter's) RC parish. To find the most likely graveyard, I'd suggest asking the Roscommon list or checking Mitchell's book on Irish graveyards. Diane
