Information I've seen on WikiTree shows that JohnSinclair, son of George Arthur Sinclair of Mey and Margaret Forbes, was married twice (to: 1. Catherine Fraser and 2. Christian Mowat) - with no son by either. Info from Peerage.com does not show him married to a Marion McCath. If this is true, then they could not have had a son named Thomas, b. 1618, who became father of Thomas, b. 1651 or 1663 in Tillicoultry because this John Sinclair daughtered out. Please help me see where the error is. Thank you. J Sinclair
