I have a Mary Grealy, ( baptised June 1795 ) in Tuam, daughter of John Grealy and Eleanor Hynes. She married Patrick Stanton, Annaghdown, and produced Michael, ( baptised Oct 1811 ). I can't find any trace of the family after 1857 when John Stanton, son of Michael emigrated to New York. Let me know if there is any connection to your Grealy's and would appreciate any information as to whether they remained in Galway or went elsewhere.
