Can't you talk to your cousin and offer to buy the stuff? Perhaps if you
mention how much it means to you, the cousin would be willing to work with
I think I might ask "what would you be willing to sell the cradle to me for?
I really hate to see it pass out of the family." You need to take a look at
it all and decide what you want, how much you are willing to give for it, and
discuss it with your cousin. You will pay far more at an auction.
