Not sure, David.
Provided William was prepared to acknowledge his fatherhood, the child may well have been baptised as his. I have a few such instances in my own tree, as some of my ancestors - especially my Cambs ag labs - were very naughty!
I have drawn a complete blank on Thomas 1756 of Upper Gravenhurst, and his wife Phoebe. There are a few Wisson/Wissen/Whisson folk in Beds, but no Phoebe. The only record of their "births" in the IGI are member entries extrapolated backwards by 25 and 20 years respectively from their marriage entry - totally unreliable in my experience. There are also Wissons in Cambs, but still no Phoebe.
One thought, which I have looked at briefly without success is that Thomas was at least 10 years older than Phoebe. Her birth, according to 1851 census, was about 1770, some 14 years after his apparent birth of 1756 calculated from 1841 and the NBI death record. Was she a second marriage? No matter really, I guess, because even so, I can't find him! LOL.
I hate to say it, but more and more he is looking as if he fits between William born 1754 and John born 1761/2 in Wilstead to John and Edith. Especially as he named his eldest daughter Edith.
JohnP - I also have Mary as the other surviving child of John and Sarah, but couldn't see a marriage or a burial for her. I tried to be brief with my outlining of the family earlier.
But oh, dear, consumption and smallpox. What privileged lives we lead these days by comparison.
I think I will stick these "unproven" Armstrongs on my website so you can both look at what I have found in detail, rather than trying to explain it here. I daren't hook them into my tree proper on G-R or whatever, as god knows what errors it could bring about if it's not correct!
Now that John and I do seem almost 99% sure to be related, I have opened my G-R tree for John to look at all my horrible Armstrong descendants!
