...his daughter who died of Pale Complexion Disease That Does Not Compromise Attractiveness...''

Tuberculosis was the main culprit because it made your character "pale and weak with a tendency towards falling luxuriously onto nearby furniture" so Lucy catching Victorian fainting lady disease wouldn't have raised to many eyebrows at the time.
