Bev, there is quite a lot of information in the IGI about this family.
There is also some information at FreeBMD (
www.FreeBMD.org.uk).
I have added the above information to my GenCircles file at:
www.gencircles.com/users/kevinbean/5The next obvious step would be to find the family (Aaron, aged 1) in the 1841 Census, possibly Hawnby.
