I would be interested in finding a death date and a maiden name for Menno Keller's wife Mary Ann. I think from Census information they came to Michigan from Waterloo County, Ontario in 1875. They are on the 1880 Census of Mancelona, Antrim, Michigan and on the 1900 and 1910 Census of Boston, Ionia Michigan. I suspect Mary Ann died about 1915 but not sure if it was in Michigan or Indiana.
On the 1910 Census of Boston, Ionia, Michigan are:
Keller, Menno, Head, Male, White, aged 59, Married Once, 35 years married, born Canada, Father born Pennsylvania, Mother born Pennsylvania, came to the States in 1875, speaks English, Farmer
Keller, Mary Ann, Wife, Female, White, aged 61, Married Once, 35 years married, 4 children, 4 children living, born Canada, Father born Germany, Mother born Germany, came to the States in 1875, speaks English, no Occupation
Keller, Clara, Daughter, Female, White, aged 28, Single, born Michigan, Father born Canada, Mother born Canada, speaks English, no Occupation
Thanks for any help,
