Alexander Sinclair of Stamster, Dunbeath, etc. (d before 1541)
m. Elizabeth Innes (d c1557, "no doubt of the family of Innes of Innes")
1. William Sinclair of Dunbeath (d 1608)
  Henderson reports that Douglas suggests that William's 1st wife was Beatrix, dau of John, Earl of Sutherland, but adds that "according to Gordon, who is the more reliable authority in this instance", she was a generation earlier ...
  m1. Beatrix (Gordon) ( dau of Alexander, Master of Sutherland, sister of John, Earl of Sutherland)
  m2. Margaret Innes (dau of John (sb Alexander?) Innes of Innes by Elizabeth, dau of John, 5th Lord Forbes) ## see here ##
Henderson reports that "it has been supposed that by his first wife, Lady Beatrix Gordon, he had William, Richard, and George, and by his second wife, Henry and David. It is certain, however, that William was son of the second marriage." We presume to show all of the sons as by Margaret Innes.
