Unknown Kyle family members

The photo was passed down through the famliy and was taken by The Rise(?) Art Studio in Rapid City, South Dakota.

The current owner of the photo believes that it is John Kyle (b.1815) and his wife Eliza Brown. It may also be John's brother William Kyle (b.1818) and his wife Mary Jane Wood. It could also be none of the above!

Does anyone recognize these people? Other names related to this family are Stephenson, Wood, Brown, Sheard.
