Most of my knowledge of the era is based on novels, in which the heroines are typically in their late teens and marry between 17-20. I would love to be better informed, do you have a source you could recommend for this information? I'm also wondering about statistics for different variables. Such as first marriages vs. average marriage ages which include widows re-marrying (especially since there's a war going on) or class differences (would a gentleman's daughter be expected to marry sooner? Would ladies who attended the London season be expected to marry earlier than girls who remain in the country? etc).
