I believe the Saul you are speaking of is Solomon Harris born 30 May 1888, died 29 August 1956. He was married to Caroline Lucindy Summerford, born 18 August 1878.
I have read where a Solomon Harris worked for the Summerford Pottery Co near Bexar on the MS/AL state line during the 1920's and 30's I believe.
Solomon was a brother of my great grandfather Richard "Rich" Lafayette Harris (b. 1886 d. 1972)
I know that Solomon's parents are buried at James Creek Primitive Baptist Church Cemetery in Itawamba Co. MS
His parents were William Henry and Nancy Jane Sanderson Harris. Solomon's grandparents were Leroy Maldin and Margaret/Margret A. Friday Harris. I visited James Creek Cemetery just last week and took photo's of their gravesites if you'd be interested in me emailing them to you. Not sure where Solomon is buried but I'm sure I could find out ...
