I have done just a bit of research into this profile. Looking in the change log I see that the current biography with the list of children was added in August 2017. This information was copied directly from page 1673 of the cited source -- a formatting mistake makes the list appear incorrectly. What looked like the 5th child of John was actually the fiths child of his son, Daniel. I have cleaned up the formatting and moved some info to the son Daniel and the grandson, Silas.
