Many thanks Elwyn,
I found these placenames on a transcription of their grave markers in Pawtucket, Rhode Island, America. Sounds like Farney is the same as Ferney. Unfortunately, not sure what the proper townlands are.
A friend online suggests that James is the brother of Father Francis Keelaghan (1804-1882), the priest who founded the Church of Immaculate Conception in Bonduran, County Donegal.
