I can help you quite a bit but I need some full names and dates of birth from your tree. Julius Levi Ainsworth b. 19 June 1893 and d. 1954 in Smith Co, MS. His father was Harvey Orange Ainsworth, b. Apr 1872 and d. 19 Nov 1940 in Smith Co, MS.
I have partial names on Julius Levi's children and approximate dates of birth. One I have listed only from a census record that was hard to read that may be your grandfather. I have him as Ulius R. Ainsworth born about 1921 in Smith Co. I suspected the first name was Julius but now that I see your listing I am wondering.
