Margaret Adams obituary in the Kalamazoo Gazette, March 4, 1916, states "She located in Detroit when she came to this country and she married Thomas Adams. Later the couple moved to Galesburg, Mich. and resided on a farm near that village until the death of Mr. Adams." He died Oct. 11, 1893. Perhaps the obituary is incorrect.
The 1870 census has them living at Richland, Kalamazoo County, Michigan.
It is confusing that the 1910 census has her as Margaret Simakian living with her daughter, Mabel McDougal. At her death she was called Margaret Adams and Mrs. McDougal was one of her daughters.
