Not sure if he was related to Blair of Dunskey Castle. ............................ (From Minutes of the General Assembly) AD1644. The Scottish Assembly commissioned the ministers to visit the Church in Ulster - Mr. George Dick, minister at Glenluce (Wigtownshire), Mr. John Dick, minister at Inch (Wigtownshire), Mr. John Livingston, minister at Stranraer (Wigtownshire) beginning Feb 1645.
Not sure if Sir Robert Adair was a member of the General Assembly from about AD1642 ?
More on Livingston in "History of the Presbyterian Church in Ireland" p.449,Google book.
There was a Matthew Adair connected about late 1500s to the Sir Robert Adair family, but I thought he had died in the early 1600s.
