While researching and searching through will and estate settlement books, have you ever encountered the Estate Inventory? If you are lucky, there has been one.
In the inventory, items are usually listed as what was sold, the price, and the purchaser. Look at these inventories closely. If you see the same last name as your ancestor, the person may be a relative. Or, if you know the maiden name of your ancestor, and the purchaser has this last name, they could be her relative. And, the list goes on. Do you see any last names of the children’s spouses? What about brothers or sisters of the deceased?
