Finlaggan Pursuivant of Arms is the private officer of arms of the Clan Donald in Scotland.
The office of Finlaggan Pursuivant is held by Thomas Miers, who was appointed at a ceremony in Edinburgh on 25 July 2009. Miers succeeded Adam Bruce (b. 1968) following his appointment as Unicorn Pursuivant. Bruce was appointed by Godfrey James Macdonald, 8th Baron Macdonald of Slate, Chief of the Name and Arms of Macdonald and High Chief of Clan Donald. This post was revived in 2005, after 510 years, in a ceremony attended by Ross Herald of Arms in Ordinary from the Court of the Lord Lyon and the four MacDonald chiefs.
