Willet Gray may have been a relative of Samuel's mother Catharine Caroline Gray.
Image is of Samuel Richard Gavin plowing his land in South Dakota.
Not sure if this is Samuel Gavin and his wife Josephine Emerson (Josie). It was with the images of Catharine Gavin and John Gavin.
Catharine Caroline Gray Gavin is the wife of John Henry Gavin.
Fourth from the left are Ellen Dayton (1855) and then Frank Dayton(1869). Their two girls Iris (1907) and Doris (1910) 10 and 7 years and are at the right side of the picture with their Uncle Claude Dayton. (Possible that Asa (1834), Cyllene and another of their sons Benjamin, William or Guy are in this photo?)
Phil Whyman in a military uniform. Friend of the Dayton family.
Sam Gavin and moose heads. Back of the image is addressed to Alice.
This is probably John Henry Gavin. It was with an image of Catharine Caroline Gray Gavin. John Henry was her husband.
Malcolm, Alice and Lottie Gavin. Could be South Dakota
