MacThomas Clan History Thomas, a Gaelic speaking Highlander, known as Tomaidh Mor ('Great Tommy'), from whom the clan takes its name, was a descendant of the Clan Chattan Mackintoshes, his grandfather having been a son of William, 8th Chief of Clan Chattan. Thomas lived in the 15th century, at a time when the Clan Chattan Confederation had become large and unmanageable and so he took his kinsmen and followers across the Grampians, from Badenoch to Glenshee where they settled and flourished, being known as McComie (phonetic form of the Gaelic MacThomaidh), McColm and McComas (from MacThom and MacThomas). To the Government in Edinburgh, they were known as MacThomas and are so described in the Roll of the Clans in the Acts of the Scottish Parliament of 1587 and 1595 and MacThomas remains the official name of the Clan to this day. The early chiefs of the Clan MacThomas were seated at the Thom, on the east bank of the Shee Water opposite the Spittal of Glenshee, the site thought to be that of the tomb of the legendary Diarmid of the Fingalian saga, with which Glenshee has so many associations.
