I so wish this was William's first marriage, but as he was born in 1775, it definitely isn't

As he would only have been 19 years old when he married Lydia, his first marriage must presumably have taken place some time between say 1791 and 1794. I've no luck so far in Bucks but did wonder if he had married 'over the border'.
Of course the Ann Nash burial may still turn out to be his first wife....
Thank you again and also for the banns info.
