Deborah; You might look up the website for the State Treasurer of Oklahoma and check the unclaimed funds and check under every name you think they may be listed under. I have recovered some mineral rights owned by my Grandfather and stepfather which we did not know they existed just by checking the fund for names. If you find a name that you think could be associated with you they have a claim file system online you can fill out. It may take a month for them to get back with you, but if you file a claim with them just keep in touch.
