Thanks for the extra info - I think I've gone as far back as I can without having to pay for it.
I've come up with a theory as to how Thomas ended up in Prescot.
As luck would have it, when I first discovered Thomas' records I was reading Peter Ackroyd's history of the civil war & had just read a mention of how north Lincs (where Blyton is) was a royalist area. If Thomas decided to join up (he wouild have been in his mid-20s), the main royalist army in the north was the Earl of Derby's. At the end of the war, he must have found himself in the Prescot area & settled down with a local lass. Pure speculation but it seems the most likely scenario.
@ Kirsty - glad I could help, good luck with the rest of your search.
