This picture is of Margaret Wark and Thomas Foster my husband's 2 X grt grandparents. It was provided by the nephew or maybe grand nephew, (we aren't quite sure) of Margaret Wark
It looks like it has been cut out of a larger photo and then put on a white background and photographed, or maybe photo copied. They married in 1867, this may have been an engagement photo. They were both about 28 years old when they married.
Location: Renfrew County,. Date: 1867.
