Marion McCath was supposedy the wife of Sir John Sinclair of Dunbeath, and mother of Thomas Sinclair, b. 1618 in Edinburgh. I show John, though, marriedonly to: 1) Catherine Fraser and 2) Christian Mowat, neither of whom bore him a son named Thomas (or any son at all). Please help me figure out what happened, here. Can't find any record of Marion McCath anywhere else. Thank you.
