This version also appears in Grants "Tartans of the Clans of Scotland" (1886). D.W. Stewart said (in 1893) "It was the earliest known to have been worn by the clan, and is reputed to have been worn in two forms; as a clan tartan with a white ground and as a hunting tartan with a grey ground. It appeared first in Smiths work of 1850 "Authenticated Tartans of the Clans and Families of Scotland" but with azure in place of the grey (see #5922). This sett is called at times MacPherson of Pitmain or Breacan Glas (Pied Wagtail) although recently discovered notes from Clan MacPherson say that Breacan Glas referred to the white dress tartan "Long before" the Vestiarium Scoticum appeared.
This tartan dates to "Pre 1819."
