E: de Atholl, 5th of Glenerochie, 1st Chief (a 1346)
Duncan is generally accepted as the first Chief of the Clan Donnachaidh which took its name from him. In the early 15th century when (for the first time) many families chose lasting family names, the head of the family was Robert (4th Chief) and members of the senior family in the Clan took Robertson as their family name. In support of their chief, many of their kinsmen took that name also although others preferred names such as Duncanson or MacDonachie.
