Children of Jonathan William Jr. and Mrs. Sarah Spring: Jonathan, d. 1767.
[Note: the assignment of this death record to Jonathan is based on Jackson's say-so. But Jackson is not a very reliable source. In this case, note that "Jonathan Jr." m. 1788 Mary Woodcock, which is right about when a person born in 1767 would reach marrying age. On the other hand, Jackson says the father d. 1776, and may be wrong, as explained on the father' page. In fact, since no children appear to be born to Jonathan and Mary, perhaps the son did die in 1767, and the 1788 marriage was the father remarrying?]
