The back says "Sarah and Winchester Massey. Sarah is half sister to William Wood."
I believe that Sarah would have been the daughter of Israel with his first wife Elizabeth Jones. They were married on February 6, 1838 according to the Indiana State Library's Marriages through 1850 database.
A quick check on Ancestry indicates that both Sarah and Winchester died in Littleton, Arapahoe County, in the early 1900's--Sarah in 1907 and Winchester in 1911. Since they are actually very distantly related I haven't verified this. Ancestry does not list any children for them.
