No, the family has no legal right to anything anymore. If they try to put any stick about, tell them to direct their inquiries to the executor of dead guy's estate. This is the person who was responsible for providing notice of the estate sale once the deceased's debts were fully discharged. The estate debts should have included your own bill for cleaning the place and removing stuff, which is expensive. If they press further, suggest you might be willing to make a list from memory of certain items that never made it to the estate sale ... for a price. Time is money.
