Hi Kate
Thank you for the possible marriage.
I've not looked at these people for quite a while and guess I must have found them on a census but that info's not on my tree
and I don't have Ancestry at present ~ just the 1911 census from FMP.
I have three children all born in Sheffield :
Maria Sutton Oates ~ 17 March 1829
Anne Sutton Oates ~ 25 April 1831
Frances Sutton Oates ~ 11 Oct 1833
I followed the 3 children and was in touch with Frances' descendant for a while
Oooops YES I do have the marriage 4th August 1823
