I have a Mary Cheeseworth who married Francis Warren in 1802 South Hill Cornwall & had a daughter Nancy (Ann) Warren (1803 South Hill). Nancy married a Thomas Pascoe.

The Cheeseworth's is in a small detached part of my family tree & I am trying to trace it as far back as I can go. There are no other details of Mary's parents & etc. Can anyone help? It would be much appreciated! Thanks.
