Did your Margaret Keating, by chance, have a sister named Harriet Keating? Harriet was the wife of my great-grandmother Margaret Warburton O'Brien's nephew, Douglas Cummings. Douglas was born in Danbury and also died there in 1955 and is buried in St. Peter's Cemetery in Danbury. So far, I have not been able to find any more on Harriet Keating. Is there a connection? I don't know if this will mean anything to you, but Douglas Cummings parents were Watson Cummings & Melissa Warburton. Thank you.
