I was sorting old hand written records of my great Uncle Oran Bains (son of Wyley Bains who was the youngest boy of Henry/Pinkney) and found this entry -- Bell Whitehead married Jeff Shannon and raised 4 girls 2 boys Lola, Laura, Katie, Rosie, Fletcher, Andrew, Admiral.
I know this may create more confusion, but you are connected to the Henry/Pinkney family. I would love to hear more about your line if possible. If I find any more information, I will let you know.
I have also found a "note" saying that Mary L. Bains may have married a "Davis". Pinkney Bains lived in Hutto,TX until she died.
Redmond was the son of Henry Sr. and brother to Henry Jr.(Ido have more info.)
