John Catt and Amy Rust

I am looking for information about John Catt (my 6th great grandfather), who married Amy Rust in 1754. Their son William Catt married Sarah Hunt in 1796. William and Sarah had a daughter called Sarah Catt, who married George Watkins in 1826. Sarah and George had a daughter called Sarah Ann Phillis Watkins who was born in 1828.
I am looking for any information about these people and would be happy to hear from anyone who has any.
