Diane, I have a Susanna McIlwee born 1883 in Calderhead, Scotland. Also, in 1856 a Susan McIlwee marries a John McDavitt in Clyde, Glasgow, Scotland. If you are tracing either McELwees or McIlwees, I can assure you that you will end up back in County Donegal, Ireland. Everyone I have come across who are tracing these names always end up there. P.S. I have a daughter Suzanne McIlwee. Good Luck, Roy McIlwee, Scranton, Pennsylvania.
