The home of Henry Benjamin Gaines in Brown County, Texas with his family pictured. 

Please note the empty chair before Mary Jane "Mollie," signifying that she is a widow.  It can be assumed this picture was made soon after the death of Henry in 1911.  I've made this assumption based on the approximate age of Carey (third person from the right) who would have been five years old when his father died and he doesn't look much older than five in this picture.

The three grown men are the unidentified sons of Henry and his first wife, and the other people in the picture are (l to r) Maggie, Martha, Novella, Widow Gaines, Hattie Mae, the family dog and Carey Gaines)
