Anyone know how to contact L.Clay Fisher in Houston Texas?

He had leases with my grandparents various 130 plus acres. They have passed them down the minreal rights and surface rights to us grandchildren we reside in Washington State. The acreage is in Starr County, Texas. I have requested a title, lien, and tax search on the information I have to get the ball rolling any information would be appreciated. Thank you Lone Star in WA
