The baptism of the son Mark at Warenford Presby probably has the best information for you:
Mark Sanderson baptised 25 Sep 1827 4th child, 2nd son of William Sanderson, Hind of Glororum but a native of South Sunderland and Ellen Gardener his wife a native of Newcastle, was born 20 Sep
I am not sure what to think of this one as there is a change in the wife's name but where she was born is the same. Helen is a derivative of Ellen and Elleanor
John Sanderson baptised 7 Mar 1830 5th child and 3rd son of William Sanderson, hind at Warrenton, parish of Bambro but a native of South Sunderland and Helen Blakey his wife a native of Newcastle was born 26 Feb
The baptism of William at Warenford Presby states he is the 3rd child and 1st son of William Sanderson and Ellen Gardener his wife was born 17 Oct 1825. Interesting as there is a baptism in Bamburgh C of E that says William Sanderson born Saddler's Hall, baptised 14 Nov 1825 s/o William and Eleanor Sanderson, Husbandman
I have not found the earlier daughters or the marriage.
