Thats all really helpful. I will amend my record for the date of Samuels birth.

Do you think my theory concerning a first marriage by Thomas to Ann Finch and his lineage back to Wiliam Watkins and Margaret Maybury is correct?

Finally, I have been looking for Sarah Cross. There aren't any records of a baptism at Westbury on Severn. There are two records in the FOD about the right time:

at Mitcheldean 1771
at Linton 1775.

Having asked that I had better stop bothering you. I am most grateful for the prompt answers and all the help.
