David - I have a record of the Willis marriage of which you write. It is my understanding that Charles W. Willis married Mary Rebecca LeCompte(1862-1944) and they had a son Paul Willis who married Ada Hicks. Paul died before his mother in 1933, also leaving his wife and three children: Paul L. Willis, Jr., Charles Hampton Willis, and Willis T. Willis.
Would love to learn more and share anything of interest in the LeCompte line. I am working hard to document all descendants of Moses and Elizabeth Wheeler LeCompte.
As you clearly know, Mary Rebecca LeCompte's parents were 2nd cousins. Mary's husband Stephen Barnett LeCompte was my gg-grandfather's first cousin, which I guess makes me a 5th cousin of any children of Paul, Charles Hampton, or Willis.
