Bob, I am the primary researcher for the Basford website (http://www.basford.org/genealogy
). I think that you are correct that Harry and Helen would be the children of Henry Orlando Basford. Here is some information on that family in our Basford database:http://www.basford.org/genealogy/jacob-basford/JacobBasfordR...
R. B. Basford would probably be Henry Orlando Basford's brother Rutillus Brett Basford:http://www.basford.org/genealogy/jacob-basford/JacobBasfordR...
I am not sure where the other names might fit in.
I don't believe that I have been in contact with any descendants from this line. If you wouldn't mind, I would love to get scanned copies of the Basford photos so that I can include them on our website (http://www.basford.org/genealogy/photos/photohome.html
