Once again Lynne, I have to thank you for your invaluable advice.
Mind you, I think at the moment there are a few too many rocks, and I am
probably stymied until Thomas's marriage certificate comes through.
Using the IGI batch numbers, I have now checked every parish within a 10
mile radius of Burton, bearing in mind that in those days the only means of
transport would have been walking, and have found a few Thomas Evans, but of
course without his father's name, I cannot narrow down my search. What I do
find surprising though is that I cannot find any records for the baptisms of
the children of Thomas and his wife Jane.
No doubt all will be revealed in the passage of time.
