Granville McPherson was a Deputy U. S. Surveyor in Arkansas in the 1850s. He was a chainman and compass carrier on a number of GLO surveys in Arkansas in the 1840s. I have researched all of his survey notes, which contain colorful comments about frontier life in Arkansas, as well as the trials of surveying. Currently, I am working on my third article about him for the Arkansas Society of Professional Surveyor's publication, "Point of Intersection". I have been able only to find the sketchiest information on his activities in the Indian Territory between 1861 and April 1874 when he became editor of the Oklahoma Star newspaper in Caddo, Oklahoma.
