I worry about her health though. Charlotte and Marguerite seemed to be the healthiest of Claude's girls (Charlotte died of an attack of measles, while Marguerite outlived all her siblings). I'm not sure what Louise died of so she might not be well suited for marriage (Claude had a boatload of health issues, so if any transfer to Louise or she's the equivalent of Madeleine I can't really see marriage being an option- François tried to prevent Maddie from going to the altar with James, probably would've tried to block any marriage citing her health).
