Marriage lookup please, Sedgwick

[casasantabarbara]

Hi,
I am looking for the marriage of George Sedgwick (christened 18 May 1781, Helme, Ormside) and Jane.

I have them on the 1841 census in Old Hutton. Her age is given as 50, so a birth between 1786-1791, and she was born in Westmorland.
They had their children christened in Crossby Ravensworth.
William 11 Feb 1816
George 27 Dec 1818
Thomas 20 May 1821
I have checked the IGI's to no avail.

I would be grateful for any help finding this marriage.
Thanks
Cas
