Thanks for the BP information. Frustratingly, one of the remaining unclaimed royalty payments was from BP to the guy that had died 17 years ago! I furnished the necessary paperwork for them to reissue the check to my daughter, but they have refused to answer my questions as to WHAT the royalty was being paid for! I need to know the mineral rights location etc. Perhaps your link will allow me to speak to someone in person to see why there is such things happening.
