 However, historian Alexander Mackenzie does not mention Henry Munro as a son of Robert in the Munro of Killichoan chapter of his book, "History of the Munros of Fowlis" (Foulis) (1898).Fisher and Mackenzie also give different lineages for the connection of the Munros of Killichoan back to the Munros of Foulis Castle.According to Mackenzie the said Robert Munro was the son of Alexander Munro, 2nd Laird of Killichoan and that the Munros of Killichoan descended directly from George Munro, 10th Baron of Foulis (d.1452).
