James Magill was born in Augusta County, Virginia, in 1756. He was of Scotch-Irish descent and a son of William Magill. He served in the Revolutionary War as a member of the Twelfth Virginia Regiment of foot, under Colonel James Wood, as shown by the following certificate from the War Department at Washington :
The Military Secretary's Office.
Washington, D. C. November 6, 1906.
"It is shown by the records, that one James Magill (also borne as James McGill), was a member of Captain Jonathan Langdon's Company, and of Captain Benjamin Casey's Company, Twelfth Virginia Regiment of foot, commanded by Colonel James Wood, Revolutionary War. His name appears first on the roll, dated September 3, 1777."
Soon after the Revolutionary War, James Magill emigrated to the "New World west of the Alleghanies," as the great wilderness of the southwest was then known, and along with other hardy pioneers, he made a home for himself in what is now known as Greene County, East Tennessee. The most stirring chapter of the history of the early days of Tennessee relates to the period from 1784 to 1788, when the settlers west of the mountains set up the free and independent State of Franklin, and ignored the authority of both North Carolina and the United States. The first legislature of this short-lived State met in Greeneville in 1785, and our grandfather was in the thick of the stirring incidents of these strenuous times. He had five brothers and one sister, names not known. His stature
was six feet ; weight, about 190 pounds ; fair complexion, black hair and dark blue eyes. His first wife was Betsy Evans. Their first child, Margaret Magill. was born February 10, 1784, and was married to Adam Wilson. Their second child, William Magill, was born September 13, 1785. These were the only children of James Magill's first wife.

It may be possible to confirm family relationships with James by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with James:
