Much success on your presentation Johnette.
I will take more time to explore your findings on Wallace and on ONeal.
The ONeal is of particular interes basd on the name Peter. Richard Slater had a middle name of Peter hmmmmm Also a number of male relatives are given names of Peyton [Peter] Most interesting.

This Freedman Bank record is also interesting

You have just maybe stumbled us on to something.
Interesting that ONeal is a carpenter. May be a stretch but.....
=============
I have briefly looked at Wallace. Will seek a closer look. I see a Henrietta mentioned in Court papers frequently. Might she have been a Slater? She may the mother of Nelson Slater....
