This is Elizabeth "Betsy" Kukendall and her husband, a chap with the last name Chapman.
I don't have much on her/them. She was born in 1844, and the brother of James E. Kuykendall (Picture of he and his wife Frances Tyson viewed earlier) and married Mr. Chapman and they moved to Alabama where they had a store. This picture of them is standing in front of that store.
I don't know if you can see it well or not but in front of the window to your left is a transparent blur. Is it a person that was there for a short time in the photograph that had its lens opened a long time with a small aparture for the photograph or is it a ghost?
