The chief of the clan Challum or the MacCallums, an Argyleshire sept. originally styled the clan Challum of Ariskeodnish, is
Malcolm of Poltalloch, whose family has been settled from a very early period in that county. One of this house, titled Zachary
Uad Donald Mor of Pultalloch, was killed May 25, 1647, at Ederline, in South Argyle, in single combat with Sir Alexander

Leslie advanced into Kintyre to drive out the royalists, and was renowned in his day for his great strength. It is alleged that he
slew seven of his assailants before he was himself slain. He was getting the better of Colkitto, when a Maclean came behind him with a scythe and hamstrung him; he was then easily overpowered.

In 1414, Sir Duncan Campbell of Lochow granted to Reginald Malcolm of Corbarron, certain lands of Craignish, and on the
banks of Loch Avich, in Nether Lorn; with the office of hereditary constable of his castles of Lochafly and Craignish. This
branch became extinct towards the end of the 17th century, as Corbsarron or Corran is said to have been bequeathed by the
last of the family to Zachary MacCallum of Poltalloch, who succeeded his father in 1686.

Dugald Maccallum of Poltalloch, who inherited the estate in 1779, appears to have been the first to adopt permanently the
name of Malcolm as the family patronymic. Besides Poltalloch, the family possesses Kilmartin house and Duntroon castle, in the same county.

Charles I., Sir John Malcolm, eldest son of John Malcolm of Balbeadie, acquired the lands of Lochore in the same county. A
branch of the Malcolms of Lochore and Innertiel settled in Dumfries-shire.

In 1746, Sir Michael Malcolm, baronet, being related to the last Lord Balmerino, was sent for to be present at his execution on Tower-hill. A daughter of Lord Chancellor Bathurst saw him on the scaffold, and fell in love with him He subsequently married
her. Sir Michael sold the estate of Lochore, which subsequently came into the possession of Mr. Jobson, whose daughter
married the 2d Sir Walter Scott, baronet.

On Sir Michael's death, the title devolved upon James Malcolm of Grange, and at the death of the latter in 1795, upon John
Malcolm of Balbeadie, descended from the youngest brother of the first baronet. Sir John's son, Sir Michael Malcolm, married
in 1824, Mary, youngest daughter of John Forbes, Esq., of Bridgend, Perth, and with three daughters, had one son, Sir John
