Attorney needed for transfer of mineral rights in multiple counties in Texas due to an inheritance

We have valid deeds, and would like the best way to transfer to 4 siblings. The will is from Illinois, the siblings are from various states. All but one deed is in a trust, but one was in a personal name. One area has oil production, the others do not at this time. The Counties involved are Dimmit, Anderson, Webb, LaSalle and Houston. Can someone suggest an attorney, or even ideas as to how best to accomplish this properly?

If the will was probated in Illinois, hire an attorney to draft and file deed of distribution in each child’s name and make sure to file each document in each of those counties in question.
