Hi Evie
Thanks for looking. As far as I know William only had 2 children, George b.abt 1836 (who is the direct ancestor) and Elizabeth, b. abt 1834 (who I think died in 1851 - but I need the cert to confirm it)
I was going to add William to my 'leave it and look at sometime in the future' pile.

Then I had a read back through the posts and saw your comment about Mary Chambers. So I did a bit of searching.
Found marriages in Dec Qtr 1837 in Ecclesfield registration district (which included Dodworth and Darton) which included the names William Buckle and Mary Chambers. What if they were both on a second marriage with George and Elizabeth being from Williams first marriage and the 10 year old Mary Chambers being Marys daughter. Curiosity is getting the better of me so I am going to raid the piggy bank and send for the cert.
I then went back to look at the 1841 census where Inn keeper Sarah Chambers has George Buckle living with the family which included Janet Chambers b.1825.
Also found a marriage between Janet (Jennet) Chambers and Richard Buckle in 1844. Tracked them through later census - he gives his birthplace as Farnham, same as William and she gives hers as Darton. In 1841 Richard is living with Walter Buckle and family in Brearton, Knaresborough.
Looks like there is a link between the 2 families. Just a shame it is all happening just the wrong side of 1837
