Ross Family History Fact and Researched Theory

I will start with what I know… My dad, Daryl Ross, was born in Houston, Texas and grew up in Pearland until his brother Eddie died and his dad got a promotion at Sears if they moved to Oklahoma City, which they did when my dad was 7. My Papa Guy was born in Lott, Falls, Texas and his dad Burton died when he was 11. He grew up working the farm with his mother and siblings and applied for a hardship license to be able to drive early to make deliveries for the farm and operate the tractor. He eventually went to work for Sears in Houston and met my Grandma Jo Nell Burchfield. My great-grandfather Burton McCutchen Ross was born in Indian Territory, but moved with his mom Virginia Mattie McCutchen (Ross) to Lott, Falls, Texas as a little boy. From what we have been told all our lives we are in some way related to Chief John Ross. From what we have found through census records and research my great-great grandmother Virginia Mattie McCutchen married two brothers, because my biological great-great grandfather Lee John Ross apparently died after their first two children were born, my great grandfather Burton and his younger brother Lee. Then, she supposedly married Lee’s younger brother John Andrew Ross. We also have found that the GW Ross listed on the census records is George Washington Ross who we believe moved to Texas possibly during the Starr Wars and we have found documentation that he served in the Civil War with Stand Watie. After many years of research my second cousin found that my great-grandfather Lee had moved to Indian Territory because he was employed as an Indian Agent for the Cherokee Nation at the time when my great-grandfather was born. From what I have found at this time (the 1880s-1890s) the Cherokee Nation had the autonomy to elect for the agents to be of Cherokee decent and yet, the US Government also required that they have English education and mixed heritage, which would fit with the supposed lineage of my great-great grandfather Lee. At this time this is all I know of my Ross family heritage.
