I think I found your Stonewall Alexander. He was the son of Prater and Mary Alexander. He has brothers Archie (Archibald?), Meritt, Willis and a siser named Permelia. They appear on the 1870 Census in Owen County, Kentucky.
Inteh 1900 and 1920 Census for Hopkins County, Stonewall appears with his wife, Alice and their children.The two you mention are on teh 1920 Census.
