As a minor find, it seems that there was a heroine in historical fiction named Angélique written by Anne and Serge Golon. Her stories were published in French originally; but the first ten of the books were translated into English. They're definitely in the historical romance genre, and highly readable. http://www.goodreads.com/series/50674-angelique-original-version
They made some of them into movies, starring Michèle Mercier.
