I am related to those McGeehans. My great grandfather was Neil McGeehan and his brother's were Patrick and Connell (Condy)and his sister was Rose. All three of these immigrated to PA, USA.
Rose married Hugh Callaghan in Philadelphia which is probably the person you are related too.
Patrick, Connell and Rose also had several other brothers and sisters.
Philomena was Neil McGeehan's daughter but it was her sister Una that married Noel Manley.
