Ok, I think I figured it out.John B. Slemp, I now believe is the illegitimate son of Henderson (Henry) Clinton Slemp.That would make John B. Slemp the nephew of COL C.B. Slemp.
Still this R.L. Slemp guy is a mystery.I dont have any info on him at all.I am starting to wonder about the accuracy of the news article altogether, because it was the C.B. Slemp they mention as being the secritary to C.Coolidge that went to VMI and then UVa's law school. There has only been one C. Bascom Slemp at VMI.
I just found something interesting, though, and that is the C. Bascom Slemp mentioned at the end of the article left in his will $5000 to his nephew, Campbell Slemp.Pat, this one in the will must be the one your aunt married, so the plot thickens...
This means that COL C.B. Slemp must be the father of R.L., but, again, I have no info on any R.L. As far as I know, he only had 8 kids, and an R.L. isn't in the bunch!
