My great grandmother, Margaret O'Keefe (Keeffe/Keef) Brooks was born in Ireland abt 1836-1840 and emigrated to Norton, Kings County, New Brunswick, Canada with her parents Thomas O'Keefe and Hanora Sullivan abt 1840-41. She married Peter Brooks (from Bristol, England) in 1864 and they lived in Gordonsville, Carleton County Canada from the 1860s to their death. Margaret O'Keefe died sometime after the 1911 Census - perhaps as late as 1927. She attended, periodically, the Catholic Church, St. John the Evangelist in Johnville Carleton County, New Brunswick, Canada where all but one of her children were baptised in the 1860s-1880s.
I'm looking for confirmation of her exact date of death. Thanks in advance for any help.
