Way Back Wednesday: Samuel AVERY and Jane BIRCHALL 1806

Today's "Way Back Wednesday" post is about my gggg grandparents.  All I know about them are their names and the date they married.  Oh, and of course I know one of their children: George AVERY 1814-1878, because he was my ggg grandfather.

The couple in question: Samuel AVERY and Jane BIRCHALL.  They were married 18 November 1806 in Stoke Dameral, Devon, England.  Samuel was a carpenter.  Since the Napoleonic Wars happened between 1803-1815, he probably had something to do with building ships for the Navy.  Jane is a complete mystery.

Does anybody have any information on either of them, please?
