Claiming Ownership of Mineral Rights

About 2 yrs ago I was out in Okla doing some ancestry work and found out that my grandfather had some wells, there in Coal County.  ( I think is in Wilson, Ok?)  I did some work at Coal County courthouse to look up numerous "deeds/leases", etc to find he had approx 300 acres which he sold/gave to another; however he retained mineral rights. I found more leases that suceeded him after death in 1950- passed on to my grandmother, and then to my father/ aunt.  Both my father and aunt have passed away several years ago, but my brother and I did not know anything about these.  I drove out and saw 3 wells (along with a couple of others I'm not sure of) together on his old land-- and they still have his name on them!  I've tried to contact couple of folks in Coal county, but cannot seem to locate a mineral rights attorney, or landman who could help us to take the next step to show every we are here and exist.   We're in Virginia and that's a long way off to try to conduct business in Oklahoma--- and are very anxious to find someone in that area who would be willing to help represent us to take whatever next step is necessary to claim the ownership and go from there.  Of course we are certainly willing to pay required fees to accomplish this!  

Any help that any member here can give would be soooo appreciated!!!  Perhaps the name of an indiv who handles that area, etc?
