Clint,
In the past I have found people that at sometime worked for the County Clerks office and they were willing to research deeds for a reasonable price. Do you have any leads for Tillman County? My family was from there years ago and both sides of my mothers and fathers family had land in that county.
Richard,
Sorry, but I have no contacts along that line. My minerals/interests are in Wilbarger County and Wise County Texas. I live in Flint, Texas(East Texas). One of the other Tillman County members might chime in and offer to give you a name of someone who will help you. Good luck on your search.
