Yes, it sounds like we are distant cousins. If Lawrence was Clarence's brother, and they both had the same sister in Annette; I am the son of Lloyd (Charles) who was Clarence's son. I have heard of heloise Walker before, but never Clothithe (my my what a name!)
I believe my dad was named Charles Lloyd but switched the names in his youth to Lloyd Charles
But I have done no research of my own on this, so I don't know if there are mistakes here and there.
