This photograph is identified "Sallie Richardson." The photographer's name is imprinted on the reverse side of the photo:
My first thought was that Chas. J. Richardson, of Philadelphia may be a relative of Sallie's. I searched the 1880 Census for Philadelphia and found a Sallie S. Richardson, age 19, daughter of Joseph Richardson, 62 and wife Charles (?) G Richardson, 57. I've heard of a boy named "Sue," but has anyone heard of a girl named "Charles?" I had a look at the 1870 Census and found Joseph with wife, "Charlotte," so I am fairly sure it was just a case of sloppy handwriting.
There are four Sallie/Sally Richardson's in the 1880 census. There are 15 in Pennsylvania State. I have not accounted for S. Richardsons. I am also operating on the assumption that Sallie is not married. She seems too young in this picture. However, women married early back then, so it is possible that Richardson is her married name.
I tried to find out more about our other Richardson: Charles J., the photographer. Using Philadelphia City Directories from this period, I discovered that Mr. Richardson had his studio at 244 N. 8th Street in Philadelphia from approximately 1875 to 1880. That fits with my first impression that this was a cdv from the late 1870s or early 1880s. I was disappointed that I could not find Charles J. in the 1880 US Census. I suspect there may be a spelling variation I am missing in my search.
I found Charles J. Richardson in the Philadelphia, PA Death Certificate Index, 1803-1915. He was born circa 1827 Philadelphia and died 2 Dec. 1896 in Philadelphia. His occupation is listed as photographer. He was a widower.
Unfortunately I can't narrow this one down more than this: Sallie Richardson's photograph was taken by Chas. J. Richardson in Philadelphia around 1875-1880. Perhaps she was the child of Joseph and ?? Richardson, but we can't be sure.
