Sir Alexander Forbes, 1st Lord Forbes, had two sons of his marriage, one of whom was Provost of St Giles Church in Edinburgh. However, at present, Alexander Forbes has the profiles of two sons who are both named as Provost on some sites and sources. Balfour names the Provost as William Forbes and Douglas names him as John Forbes.
If there are no objections, I would like to merge both profiles into William, who is the lower number, and retain John as other nickname, with notes. John Forbes is this other profile.
Also, just to confuse the issue, there is also another John Forbes of Terpersie, added as a son to Sir Alexander Forbes, 1st Lord, and whom I believe descends from the missing WikiTree profile of another brother to Sir Alexander Forbes, 1st Lord, and who was named Sir John Forbes, he who married Marjory Preston, please see the Scots Peerage link....
