At an antique show in Springfield OH I found some photos of people that lived in Huron Co MI.
The first photo is by a Detriot photographer and says on the back "Wm R Stafford, Port Hope Huron Co Michigan 1896". William R. Stafford was born Nov 19, 1828, in Bath, Grafton County, NH. He married Sarah Ann Leuty and re-married Mary Demaline Leuty, sister of his first Sarah, later.
The 2nd and 3rd photos of a man and a woman are also by a Detroit photographer. The one of the woman says "Mrs William Stafford, Port Hope, Mich" on the back. The one of the man says "William Stafford, Port Hope, Mich" on the front but "Mr Durant, September 1897" on the back. And it's not the same man as the 1st photo. So perhaps this is really Charles Durant and his wife?
The 4th photo say Isaac Leuty on the back. Isaac was the father of both of Wm Stafford's wives.
