Yes, she was a young lady of the Duke Residence, but there were others even more pampered than she.
Like princesses and Commandery Princesses, truth be told, she wasn't the eldest legitimate daughter; in the eyes of the Royal Family, it was customary to marry the eldest legitimate daughters, for they were born to be eldest and thus received different tutelage.
