Richards of IL

I am looking for the children of a Amanda South and John Richards that were from South Carolina that may have traveled to IL. John Daniel Richards married a Louise Susan Woodside and lived in the County of Washington at the time of marriage and later move on to Iowa, Nebraska then Texas.

He was born in 1850 in South Carolina and I think he is the brother of a Benjamin Franklin Richards who lived in Washington Co., only 25 miles from each other and were 5 years apart. I did find a Amanda South married to a John Richards who lived in Livington Co., KY and I think this may have been their parents. John Richards died during the time of the Civil War. I have found that Benjamin Franklin parents were on the marriage records of Benjamin Frank in 1883 who were a Amanda South and John Richards. Their were no Parents for the marriage of John Daniels Richards.
