 According to Fisher, Henry Munro's father, Dr Robert Munro, was the son of Alexander Munro, Laird of Killichoan and that the Munros of Killichoan descended directly from Sir Robert Munro, 3rd Baronet (of Foulis, d. 1688).Mackenzie does however state that in 1723 a woman called Mary Bain complained to the Kiltearn Session that Robert Munro, son of Alexander Munro of Killichoan, had fathered her child, which Robert denied, but that the Session ordered Robert Munro's servants to assist Mary Bain.In contrast to Mackenzie's account of Robert Munro, Fisher states that Robert was a physician by profession, and joined the royal forces, under Lord Loudon during the Jacobite rising of 1745 against Bonnie Prince Charlie.
