Dent and Tolle Families - possibly
I have been searching for some verification of what I think about this photo.
My thoughts: Taken in 1875 of the Dent and Tolle families. Older woman at the upper far left Rebecca Hayden Dent. Next to her, William A. Callaghan. In front of him his wife, Emerine Dent.
Front row seated. Woman in black Fannie P. Tolle Dent holding Lucy Dent, born 1875. In front of her also in black Flora Dent, born about 1871, little boy in front of her Ernest Linwood Dent, born 1873. I cannot even speculate about the others. This could have been a funeral occasion as Fannie's husband, James P. Dent may have died around this time. She was a widow in 1880.
This photo was in the possession of a Dent descendant but nothing to identify it.
Photo may have been taken in Warren, Marion County, Missouri.
