My David Bickham was the grandson of a David Lawrence Bickham who was descended from Hugh Bickham of Ohio. We have a fair handle on that line back to Hugh but, while we know there are 3 other lines of Bickham, we have no firm info about Hugh's parents. Carlene Morrison has a good trail on the NJ/PA Bickhams and there is some info on the Southern line. Carlene set up a site where Bickham's can have a DNA sample and that is where we found that a fourth line is apparently avail. Sorry but no Patsy or Hazel that we know of in our Ohio line but I have only tracked my husband's direct line so can't speak for any other progeny of Hugh. I would suggest a DNA sample to the site and it might help to decide which branch to try to chase down an answer.
