I have had a look at my microfiche and found the following:
this is the only George Watson in Ireshopeburn that I could find in 1841 census:
HO107/308_10
Ling Riggs, Ireshopeburn, Weardale
George Watson 30 lead miner y
Margaret Watson 35 y
Mary Watson 6 y
Elizabeth Watson 5 y
Hannah Watson 3 y
Abigail Watson 1 y
(in 1841 the ages of adults over 15 were rounded down to the nearest 5, so George was aged between 30 and 35)
found this in BMD info I hold:
There are only the following marriages for George Watson at St Thomas, Stanhope (none at St John’s Chapel):
Mary Walton 4 June 1841(Heatherlycleugh)
Margaret Coatsworth 16.11.1833
Mary Watson 14.10.1832 (Heatherlycleugh)
Widower Isabella Shield widow 03.04.1834 (Heatherlycleugh)
There is only one baptism for Margaret Coatsworth in that time frame:
Born 02 Nov 1809, Christened 14 May 1811
Father William Coatsworth mother Frances Featherston
There is also a John Coatsworth with the same parents, born 03 June 1805, Christened 18 June 1805
There is a marriage for William Coatsworth and Frances Featherston 08 April 1805 St Thomas Stanhope.
hope this helps
