I have a feeling they would have been Presbyterian/Methodist/Wesleyan - think its all pretty much the same isn't it.
One of the daughters married in a Methodist (?) church at Seafin. No burial details. (Married into HUNTER family in Cavan). One daughter who came to Aust. married Wesleyan. Buried Wesleyan/Methodist. The other daughter who came to Aust. married in Anglican to an Anglican man, but she is buried on her own in Methodist cemetery.
Therefore there is strong indication for Presbyterian.
