I think I may have the information on my Family Tree that will assist you.
My Great Great Grandad was called Patrick McGeehan
and he was married to Mary Boyle.
Patrick McGeehan was born in Ramelton co, Donegal.
I'm not 100% sure of all the information as obviously I am not looking at it at this particular moment. But get back to me and I will see if I can help you.
Search for the McGeehan/Brady Family Tree and it should have all the information you need!
I have attached two photos of Mary Boyle and Patrick McGeehan.
