This fits with what Miss Willie Adair stated in Leo Z. Adair's Ref. 2 - A-D, p. 29
"...From there William, a Presbyterian minister, who had been educater at Glasgow College (Finis had April 3 1787) came to Philadelphia, PA as an Irish patriot and obnoxious to the British Government, he had to flee his native country hidden in a barrel. "Rev. William Adair was being chased by the King's soldiers in the County of Down, Ireland ... "James Adair, brother of Rev. William Adair of the Parish of Cumber, County Down, Ireland with his wife, who was Mary Wallace, and whose mother was Nora McDonald, followed his brother to the U.S.A. September 3, 1817."
Wonder how many Robert Adair, farmers there were in Cumber in 1785?`
