Mary J. born in 1874, married housewife, born in Michigan, died 8/ 27/ 1920 at the Traverse City State Hospital at 46 years old.
The cause of death on her death certificate reads, "Suicide by Hanging." She was buried at West Branch, Michigan.
Her parents, John & Martha, were both born in New York. Husband's name, W. A.
I find Mary J. at 5 years old living in Tuscola, Mi, along with her mother, Martha, who has remarried. Mary J. has 2 older sisters and an older brother, all from her mother's first marriage.
At this point, I can find no further information.
