What a great idea this website is, I am sure we all have bought certificates and other genealogy documents only to find that they aren’t about people on our family tree. My friends and I call such people “Ancestors I once had!!”.
With this website you can put your unwanted items online and hopefully find a good home for them and of course you can check the site for anything relating to your genealogy. You never know there might be just the very clue you have been looking for waiting to be found.
