I need the help of a historian/geographer. Or at least a good reference for the following genealogy question. My father, Harve Henry Prichard was born in 1898 in IT. Between 1892 and early 1900s, his father, John Henry Prichard (being a Baptist Minster) moved the family between this location and Tarrant Co. Texas several times . Several years ago, my father took me to the "place" where he was born and raised. By today's landmarks, the location was in present day Stephens Co., Oklahoma - some 3 miles south of OK #7 highway and 4 miles west of US #81 very near the Lawton, Duncan Y. The community and the school ( by statehood in 1907 ) were all known by the name of a local creek, "Stagestand". (I do not think it was ever incorporated as a town) Now, my question: Would this geographic location have been IT, Chickasaw Nation or would it have been in far eastern Comanche lands? From my Oklahoma History course, it seems to me that during this period, the western boundary of Chickasaw Nation and the eastern boundary of Comanche Lands was the Indian Meridian. I was also taught that this boundary was basically the route of US #81 highway At question, more specifically, would the 1900 IT census including "Intruders" cover this area? and, would that mean that my grandfather was there illegally? Any information or references to sources would be appreciated.
