Will Confusing? Look at Estate Accountings

Is great-grandpa's will confusing? Are the relationships unclear? If so, make certain you have accessed all accountings of the estate that indicate what relatives received what amounts of money. If these records exist, the disbursements may mention relatives not listed elsewhere (people tend to "appear" when money is involve). These documents may also help to clarify relationships that may be ambigious in wills and other records.
