Thank you so much for the information, I did not know David Heath had a middle name of Thomas.

I have found the cemetery entries, I think the parents of David Heath are James Heath & Harriet Huxley, as I found a marriage on FamilySearch, intended marriage date 26 aug 1832 Davenham, Cheshire.
The parents for Jane Emily Grainger, I have George Grainger & Mary Ann Boughton, but unsure.

Thanks again
