I just want to make sure you are not getting them confused -
There are two couples named of John & Sarah Keeling - one at East Retford (the marriage I mentioned) and one at Worksop. I don't think they are the same couple as the occupations don't match, and the dates conflict.
At Worksop, children of John & Sarah Keeling
15 Aug 1804 Richard (b. 19 Jul 1804)
25 Feb 1807 Thomas (b. 03 Feb 1807)
20 May 1810 Mary (b. 27 Apr 1810)
20 Jun 1813 Charles (abode Bridge St, father mason)
20 Sep 1815 Joseph (abode Bridge St, father mason)
08 Jan 1819 Samuel (abode Bridge St, father mason)
At East Retford, children of John Keeling & Sarah (nee Slingsby):
20 Dec 1812 William
13 May 1815 Mary (abode Sutton's Row, father weaver)
Which one are you related to? I can't see a marriage in Notts for the Worksop couple.
