I am researching my ancestor, Robert Henry DAVIS born in Donegal in 1865. His parents were Andrew and Ann (maiden name BUSTARD). They were married in Donegal Registry office in 1856. His father was John, her father was William. I know from his naturalization record that Robert emigrated to New York in 1869. He would have still been a small child, so probably with parents? Also, I would really like to find out what religion they were, since as far as I knew they were Catholic, but since Andrew and Ann were married in the Donegal Registry Office, probably they weren't. Any help would be appreciated.
