Hi Lisduggan,
As far as I know, Maurice Kiely of Dongarvan Co Waterford, was married to Mary (I don't know her maiden name). They went to Canada or America, where they had a son John. He later became Monsignor Kiely, he searved the church in Boston and Chicago. Maurice died in 1820 aged 67, over seas. The Family headstone in Dungarvan, has the name Kiely on it, but the McGraths are also buried there. Somewhere along the line the families are related, but I do not know where at the moment. Please let me know if there is a connection here.
Regards
Maggie
