Need attorney in La Salle County, TX to claim mineral rights

Recently found out that I inherited part of 20 acres in La Salle County, TX. Believe the remaining acres in the 20 acre tract should be mine also. Live in Alabama and need a good Texas attorney to help me claim the remaining 15 acres.

I have a good oil and gas lawyer. David Garcia in Laredo.

Not yet. Still looking for an attorney.
