Older men often married younger women! I was honestly a bit surprised by all the young men~.  Average marrying age for women I'm this time period is 20-22 by the by.

Edit:. Side note.  My plan is to make a second character based off the movie quote "And I'm sure he kept a very good sort of shop before his elevation to Knighthood.". Should he be a man or a woman in disguise?  If a woman, hella gay.

Lastly, firearms - are they a thing in this world?  We would have had muskets and such during Regency.
