The first John Adair that I have is: John Adair b.1732 in Ballymena, Antrim, Northern Ireland.He married Elizabeth Crawford in Ballymena.Together they had 4 children; Andrew, James, John and Mary. The second John (son of the first John) was born in 15 Feb 1750 in Limerick, Down, Ireland.He married wife #1 Mary O'Donnell and together they had 5 children all of which were born in Staunton, Augusta Co., Virginia; John, Margaret, Samuel, Robert (b1784) and William.Wife #2 was Elizabeth McKnight Burgess and together they had 6 children: Robert McKnight Adair (b1795 not to be confused with previous half brother above), Joseph, Peggy, Edward, Elizabeth and Nancy.All of their children were also born in Staunton except Elizabeth and Nancy who were both born in Madison Co., Ohio. There is a will abstract for John #2; Madison Co., Ohio years 1810-1825, pg 53. I don't have a copy though. He is also known as John Sr. which is confusing because that should have been his father's (John #1) title. I have counted 11 Johns between John 1, John 2, John 3, Robert McKnight, Joseph, Edward (all sons from John 2), Josiah, Henry and Preston (all from John 3)Whew!
