I just had the first practical need for the family history information I’ve assembled. The heirs for aunt Babe’s estate are all nieces, nephews, and grand-nephews, since she never had children and outlived all her siblings. The lawyers for the estate needed to know when her siblings died to establish that they are, in fact, dead. None of the living relatives were even alive when Babe’s oldest sibling Joe died in 1931. I just saved the family a bunch of money to research all of that.
