Another offering from my Etsy friend, Restored Memories. Per her description there are actually 2 photos of Mr. Robinson, which she is selling together – here’s the link to her store.
On the back of this photo is the handwritten name, Alfred T. Robinson and the location on the from is Saginaw, Michigan. While those two pieces of information alone may not always yield a good identification – what helped in this case was that Mr. Robinson never left Saginaw. From the 1900 to the 1940 census he and wife Louise/Louisa and their children are there.
Alfred appears to have been born around 1859 in Michigan. His parents were from England. But in all pre-marriage censuses (1870 and 1880) Alfred and sister Helen only lived with their mother, Mary A. Robinson. There’s no indication if she was a widow or divorced. She was from England however. Finding his father would be a great addition!
