June, Samuel Byron SPRINGER m. Julina I. Blythe on Sept 7 1860 (license issued on Sept 3) per 'SPRINGERS in the SOUTH'.
The book lists their two children as William Andrew SPRINGER b. 26 June 1861, and Thomas Samuel b.26 June 1863 d. 1926.Both sons are listed with families.
I'm not saying the book is 100% correct, but maybe contacting one of these sons' descendents might help rule them in or out.
If you are sure about JT's birth year being 1873, and the SitS book is correct on Thomas 'Samuel' Springer's name and birth year, they can't be the same person. SitS has Thomas S. getting married in 1887 with his first child by Lillie Carrell being born in 1888.
I haven't had a chance to check the 1920 census for Thomas Samuel and Lillie.Lillie supposedly d. 1935.
Have you tried to find living descendents of Edna?
