Hi. I am 5th-great-grandson of Caleb's older brother John Adam Blackwelder (b. 1719), through his daughter Mary Blackwelder, who married John Shaver. I know that D. C. William's book was very scant regarding my branch of the family. I do have a LOT of Shaver information, though. I am interested in corresponding with anyone else who is descended from John Adam Blackwelder.
