Gedney Hill Chapel 1804

A Memory of Gedney Hill.

I don't have a memory to share but hope that someone can help me with my family history search. My ancestor Thomas Dams (Dames) married Sarah Leatherland 27 Aug 1804, Holbeach, Lincs. Banns published 2 Aug 1804 - both of this Parish. (recorded as DAMES) - Gedney Hill Chapel / Minister John Dinham in presence of William Norman).
Can someone help me please. Does this chapel still exist or is it now called something else - perhaps Holy Trinity? I need to search Parish Records for a record of the marriage.
I live in South Wales otherwise I would be able to visit and check for myself.

Thanks for any help.
