Hi
I'm interested in your John Taylor of Marden. one of my ancestors is a Rebecca Taylor of Bodenham. She had a brother John christened with her in 1803, parents William & Ann. There is also a possible brother Richard christened in 1808 in Bodenham. He was probably the Richard Taylor living in Marden in several census with possibly his mother Ann in 1841. In fact he was born at a place cauld the Vauld part way between Bodenham & Marden. On the IGI several entries are 'of Marden' concening people that were christened at Bodenham.
In 1841 census John Taylor b 1801 in Bodenham with wife Elizabeth or Charlotte, children John 1830 and Charles 1833. These seem to be your John and Charles.
