There are some online gedcoms with Duncans that claim a John Duncan, supposed son of Charles Duncan, had taken his family to Texas instead of the Cherokee Nation when the families moved from Georgia to the Territory, but there is little or no documentation for their claim. This is speculation; documenation or DNA testing is needed.

My grandmother's cousins were documented and most of their Duncan family left the Cherokee Nation for California in the 1850's with a few relatives returning to the Nation before the Civil War. These cousins and their descendants would not be recognized as Cherokee today because they left the Nation and were not on the Dawes Roll. That is my interest--the families who were on the early roll and did not stay in the Cherokee Nation. Before the Dawes Commission got involved, there were Cherokees who lived in Texas, usually the mixed bloods, some were involved in Texas state and county politics after the Civil War--if the state got too involved at the county level, that person found it prudent to visit their relatives in the Cherokee Nation.
