Here’s the completed text I found in some other photos:

I found my father and one brother, William, lying dead in the road about two hundred yards from the house. I saw my other brother lying dead on the ground about one hundred and fifty yards from the house… his fingers were cut off, and his arms were cut off; his head was cut open; there was a hole in his breast. William’s head was cut open, and a hole was in his jaw, as though it was made by a knife, and a hole was in his side. My father was shot in the forehead and stabbed in the breast.
