Gotta love the 18th century for stories like these: He fights a duel to defend her honour and is fatally wounded. In gratitude, she marries him on his deathbed. Then he recovers.
International Women's Day was yesterday. If I had been blogging yesterday, I would have recommended this link to Jonathan Yardley's review of Wedlock by Wendy Moore (no relation), about the marriage and divorce of the lady in question.
Update: History Today's history of International Women's Day is here: ninety-eight years old, and started by Clara Zetkin.
