Are you trying to determine the exact relationship between Beulah SAULS and Susannah LEE?
I'm not related, but I took a look and found a Beulah SAULS b. 1891, daughter of Taylor M. and Cora SAULS.Taylor's mother was a Percy/Pearcy LEE.There's a user submitted tree for this family here: https://familysearch.org/pal:/MM9.2.1/3SRX-45H
According to that tree, Pearcy's father was John Alexander LEE.Her father had a brother, William Gadson LEE.William Gadson LEE was the father of a David Eli LEE.
If that is the same person as your David Eli LEE, he was first cousin to Beulah SAUL's mother.
