Banns are up, but start 1763 (too late!). Some entries have marital status.
The entry on FamilySearch is from a book, The parish registers of Dartford, Kent, 1561-1812, transcribed by Thomas Colyer-Fergusson
I can see the marriage indexed on findmypast, Kent Marriages And Banns. Just a transcript, don't know what more (if anything) it says
