There is a Thomas Scott who was baptised in Wakefield 10 April 1640. His father was John.
Another Thomas Scott was baptised Netherthong, Yorkshire on 26 June 1642 . Father, Thomas.
Another in Huddersfield 16 Oct 1642 to Xoferi.
Another in Sutton, Cambridgeshire on 15 Sep 1640 to William
Another in Lambeth on 17 Jul 1640 to John.
Just doing a quick search. In 1640 there are a further 2 baptisms of Thomas Scott in England. In 1641, there is just the one. In 1642 there are two more in addition to the above. In 1639 there are 3, in 1638 there are 3.
With a more detailed search, I am sure more Thomas Scotts would pop up and I cant see all parish records.
I dont think you are going to get further back, soon, with this one.
For Samuel Scott, the nearest I can get is 1680 and 1686. As I said, I cant see all parish registers.
