I have just picked up your request from last November for information on Jeremiah & Antonia Goldwell's marriage. Unfortunately I also spent much time trying to find it and so far have failed. Antonia is my 3 times great grandmother on my mother's side.
I researched Jeremiah's military career and in 1992-3 I travelled through central Spain & southern France following their route during the Peninsula war. I wrote a document about this, which I think you might find interesting.
I'm sure we have other information to exchange, so if you are still involved with the Goldwells, please get in touch. I live in Beverley.
with best wishes,
