The Clan Malcolm, also known as the Clan MacCallum, is a Highland Scottish clan. The Clan MacCallum may have originally been a separate clan until the 18th century, when the chief of the Clan MacCallum adopted the name Malcolm after inheriting the Malcolm estate, and the two clans were drawn together under the same chief.

Columba or Colmcille was an Irish abbot and missionary evangelist credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the patron saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Catholic saint and one of the Twelve Apostles of Ireland.
