Would your data include who the wife of the Oliver Calk was?
Oliver appears in the 1880 and 1900 census of Union Parish, La. In 1880 (I've posted this previously on this forum so I won't repeat all that) his wife is Martha Jane and is listed with two step sons, Solon & Bradie/Brady Ransom. Since my prior posting on this, I've found that Solon and Brady were sons of the family preceding Oliver Calk in that 1880 census. In 1900, he's as follows:
