My gg-grandparents were John Noble and Mary (possibly Nixon), through their daughter Mary Alice Noble. Mary Alice married Richard Gilder, who died 1882 in Donaldson, Michigan (Upper Peninsula, near Sault St. Marie). While researching Richard's death information, I was made aware that there were two grave markers in the Donaldson cemetery (besides Richard Gilder's):
MARY NOBLE Oct. 6, 1891 82 yrs. Native of Co. Fermanagh, Ireland
JOHN NOBLE Sep. 29, 1881 72 yrs. 5 mos. Native of Co. Tipperary, Ireland
From the Canadian census records, the John and Mary who are my ancestors were born between 1809-1811. I did the math, and both persons buried in Donaldson were born approximately 1809 - so far, so good. Also, while they lived in Canada, it was primarily in the Mulmer area. If any of this rings a bell, please drop a line. In all the family trees, I've never seen hard documentation of the dates/places of John and Mary's death - supposedly in Dufferin and/or Ontario. Lastly, I see no certain Canadian census records for John and Mary, after 1871.
