There was a Sir Robert Adair b. 1583 d. 1st March 1655 (Betham's will extracts 1656 ?), had son William bc1625 d 30th Nov. 1661, had son Sir Robert Adair II b 1659 d. 9th Feb. 1745 being 2 years old when his father died. Appears he may have been looked after by his uncle Alexander Adair.
In "Register of the Privy Council of Scotland" Vol.II AD 1665-1669, index there are entries for -

I had noted down that Alexander Adair was a "Stationer". I had also noted an Alexander Adair b.1571 acquired the lands of Corgie/Cargie, and that Ninian Adair was mentioned in a deed 12th Nov. 1595 re Corghie.
The question is, who was this Robert Adair who was an adult c.1666.
Witnesses to a deed in 1611 were Jacobo Adair de Corghie, Gilbert Adair fratre Wil.Adair.
A deed of 1614 lists Patricio Adair fratri Willelmi Adair de Kynhilt.
