Lemuel Sanders b. 1730 d.1795 Lincoln County, North Carolina might be the brother or cousin of Samuel SandersII.
A descendant of his has a 12/12 DNA marker match to D. Sanders and A. Fisher.
I have a 11/12 DNA marker match to him.
You can find his DNA test in the Family Tree DNA, Sanders/.../Sanderson Y-DNA Project; Unassigned Members #83. In the Rhodes DNA Project: y-Results there are two Rhodes that have a 11/12 marker match in Rhodes Possible Lineage 6; R-29 and R-38.
My DNA test is in Ancestry.com/DNA; Sanders/Saunders DNA Group; GRP019 (Sanders/Rhodes/Fisher).
Lemuel could be the son of Joseph the missing brother of Samuel II.
