I’m not happy to be posting something connected to Ohio State University, BUT I’d never heard of an adoption like this one and I found it rather interesting, so pardon me fellow Wolverines…
Mary C. Thorne and Family
This is a portrait of Mary C. Thorne of Selma, Clark County, Ohio, with her family. The woman standing is a mulatto fugitive slave that the Thorne family adopted. The image was collected by Ohio State University professor Wilbur H. Siebert (1866-1961). Siebert began researching the Underground Railroad in the 1890s as a way to interest his students in history.
