DNA testing of Louie's descendants can confirm ethnicity. To my knowledge, the Red River War was the last military campaign and it took place primarily in Texas? It ended, officially, in June 1875 long before Louie's birth. I'm sorry if my reaction to the possibility of kidnapping offended you. I am aware that it was also performed by Native Americans. Louie's WWI Draft Card indicates he did not know his birth place. However, the WWII Draft Card indicates birth in Muskogee, OK. His parents' birth info extracted from census data. Admittedly, that resource is sometimes unreliable.
