Thomas Batchelor Ightham 1780s and two marriages to women named Mary

[Petros]

The parish registers for Ightham show marriages for
Thomas Batchelor on 25 May 1783  to Mary Bist  and another on    17 Oct 1785 to Mary Gardiner but reveal no burials of any Mary Batchelor
8 children were baptised there to Thomas and Mary Batchelor, one in 1783 the remainder from 1791-1808
were there 2 couples or did Mary Bist die?

A dilemma to resolve unless anyone can point me to clear evidence to help

The only burial in Ightham of Thomas Batchelor in 1816 says he was born in 1750

The second marriage states that Thomas was a widower

Thanks Rosie, just intriguing as to where the burial of his first wife was
