Thanks for the help.
Which volume of Philimore is that in please.
In 1841 census John is deceased (I presume), and Ann 49 (so born circa 1791), living in Tuxford. Their children are Thomas 14, John 9 and Sarah 8. So I think they married a bit later in life, and perhaps the John I want is an older one in the IGI as christened in May 1784 in East Retford. His father was Thomas.
