Hi Declan, My gg grandmother was Margaret Quail. She married Charles Buttler, 1861 in Ontario, Canada. They had 2 sons; William Charles and George. Both Charles and Margaret died when their sons where very young. I have very little info of her. I do know she had a cousin; Mary Ann Quail b. 1859 and married James Link in Ontario, Canada and had 5 children. Could this be a connection to your Quail's?
