I was intrigued by the current postings at Progenealogists on who is and who is not Native American. Michael's family had no such tradition about being part Indian, but they do come from Oklahoma. Both his parents were born there, and he even has a real "Sooner" in his background. Michael and his parents did not know much about their family histories until I started nosing around in it. They are not part Cherokee, but their ancestors did walk The Trail of Tears.
William Morrow, whose full name is in the title, was born on 25 November 1802 in Jefferson County, Tennessee, the son of David and Priscilla (Doherty) Morrow. He married there on 27 June 1826 to Lavinia Lea Jarnagin, the daughter of Chesley and Martha (Barton) Jarnagin. All these four families; Morrow, Doherty, Jarnagin, and Barton, were influential in their day, either founding early Tennessee or fighting in the American Revolution. In any case, William became a physician and was the doctor for the Cherokees on the Trail of Tears and kept a diary of the event. There is a decent write-up on the Internet for this couple (#11). Their third son, William Lindsay Morrow, was Michael's great-great-grandfather. We may have a photo of him [i.e., William I.I. Morrow], but it is only identified as "grandfather Morrow."
