Hi, I realize that your post is several years old but hoping that you will still be here. My name is Roby Lee Whittaker, Jr. , son of Roby Lee Whittaker, grandson of Gladys Warr Whittaker Webb, great grandson of Evie Coulter Warr Luse, great great grandson of Henson Coulter. Sampson was the brother of Henson Coulter. Nobody knows exactly what happened to him. It is said he received a land grant in west texas. Then said he died young and is buried in the Coulter Cemetery in San Augustine Co., Tx. However, there is no tombstone there. Any help would be appreciated.
