Interesting. We have a Eugene Partlan/Partland/McPartland (depending on the record) who married Anne Frazer and lived in Aghnasurn and Derreenargan, County Roscommon, right across the line from Aghanagh.
He had 2 children baptized in the church at Ballinafad, parish of Aghanagh, County Sligo, Catherine in 1860 and John in 1866.
