Marie l'Englois is an Englishwoman living in France in the mid-16th century (circa 1530-1570).
Marie initially traveled to France in the retinue of a politically-climbing male relative assigned to the French court (identity of said relative occasionally varies between brother, uncle, and husband depending on random whim). When this relative passed suddenly, she managed to obtain herself a place in service to a minor noble household as a music tutor (and in later years secretly a scribe as well), and somehow convinced her remaining family that a) this was their idea, and b) it was to their political advantage for her to remain there with the remaining retinue rather than being summoned home.
Marie is educated, literate and well-read, and is mostly self-supporting with the assistance of the family she serves and the occasional contribution from home. She enjoys rather more independence than is generally considered appropriate for a lady, mostly because her remaining family members don't consider her important enough to marry off, and it costs them less money to leave her in place than to fetch her home. She values this independence and doesn't do anything to draw undue attention to herself and risk changing that. As a consequence, her family has mostly forgotten she exists, beyond the occasional letter, bit of gossip, or political machination they require of her.
Marie greatly enjoys experiencing the many music and fashion styles she is exposed to through the household she serves and the larger French court. It almost makes up for the careful politics she has to play in order to stay there.
