Hello, Don -- returning to this discussion after a very long absence, I'm intrigued to see your two posts from 2020. In brief, I can tell you that (as I suggested was likely in my earlier posts) the family of John Pavitt of Bradford Abbas is almost certainly quite distinct from the Pavords of Nether Compton. While John Pavitt, who married my 3rd great grandmother Ann Chiles/Childs as his second wife, did become the _step_father to my 2nd great grandfather -- William Henry Childs, born in 1812 -- Y-DNA indicates that William Henry's biological father was most likely one of the Nether Compton Pavords.
Specifically, the most likely candidates are two teenaged Pavord boys, Samuel or Thomas, born in 1792 and 1794 respectively: they lived perhaps two miles, at most, from Ann Childs's native hamlet of Clifton Maybank (which nestles up against Bradford Abbas). Ann was born in late 1791 or very early 1792 (she was baptized on 15 January 1792), and was thus closest to Samuel in age. Samuel would have been of marrying age by 1812, though at 20 he'd still have been unusually young; Thomas would have been barely 18... which might perhaps explain why Ann did not acquire a husband by the time of William Henry's birth.
Both Samuel and Thomas married other young women by about 1815, and it is of interest to note that Thomas's wife, Jane Woods [to whom I am related; my paternal great grandmother was born Charlotte Woods] was evidently pregnant with their first child, daughter Jane -- born in August of 1815 -- at the time of their early-March nuptials. So it is conceivable, no pun intended, that there was a pattern of behavior here on Thomas's part....
I log my research on WikiTree, where I volunteer with a couple of pre-1700 projects; you can find my profile there at wikitree (dot) com/wiki/Childs-1516. I will try to check back here for any replies or additions to this discussion, but please also feel free to send me a private message from my WikiTree page (this may require that you register on the site, which is free). My tree is public -- click on the "Family Tree & Genealogy Tools" tab, and follow the Childs line back (click on the tiny red/blue arrowheads in the righthand column to get beyond the first five generations), and you will find John Pavitt listed as William Henry Childs's [non-biological] father... simply because he is the only father William Henry ever knew, and because there is some evidence that the two became close.
I am occasionally in touch with a gent in England [I'm in the States] who would be a half-cousin of yours, as he is a descendant of John Pavitt and John's first wife, Martha Adams. If you would like, I can try to put you in touch with him; his name is James Bevan, and he's quite experienced at genealogy... and knows the Pavitt lineage very well.
Very best wishes for your research; please let me know if I can be helpful.
