I am also researching the james Mitchell line. I am a descendant and my family still lives around Trigg County, Kentucky. I am from Greenwood,South Carolina and would like to share information with you, if at all possible. I am writing a history of the family and James Mitchell's beginnings are also impossible to find. My daddy James David Mitchell was a grandson 7 times removed.
Let me know if you have any information. I will be glad to share with you all I have.
