In a book titled THE ROSTER OF TEXAS DAUGHTERS REVOLUTIONARY ANCESTORS from the Texas Society of the National Society Daughters of the American Revolution Bicentennial Edition. Vol 1 A-B Pt l. It listed James Alexander, born 1732, probably in Scotland and died March 9, 1808 in Mecklenburg, NC. Married Elizebeth Read, born 1749 and died July 12, 1823. Served as Capt. Mecklenburg County, NC.
