Friedli provides an extensive examination of “passing women” -- defined as women (using current terminology, it might be better to say “persons assigned female at birth”, but Friedli uses “women” and I will follow that here) who live, work, and/or marry as men for some period during their lives. This is specifically distinguished from theatrical cross-dressing or overt cross-dressing as a sexual signal. While the phenomenon is far from confined to the 18th century, there seems to have been a fascination with it in England, beginning in the late 17th century.
