(11) Achmuty alias Auchmuty of Brianstown

Auchmuty coat of arms
This family traces its descent from Capt. Arthur Auchmuty (1600-98), a descendant of an ancient Scottish family of that name from Fife, who settled at Brianstown (Co. Longford) in the reign of Charles I.  Brianstown was rebuilt as a two-storey Georgian house in 1731, by Samuel Achmuty (d. 1766).  The estate passed from father to son until the mid 19th century, when on the death of Thomas Gordon Achmuty without male issue, it passed to his daughter Bridget Domvile Achmuty, who married Capt. Henry Musters (of the Chaworth-Musters of Annesley and Colwick family).  The Musters seem to have sold up in the early 20th century, probably soon after the death of J.G. Musters in 1917.

The original house on the site (possibly built c.1640 or c.1654) was rebuilt in 1731 as a two-storey five bay house on a basement for Samuel Achmuty, whose arms and motto are in the tympanum above the door.  It was gutted by fire in 1922 and rebuilt in the 1930s as a single storey above the basement, with a narrow entrance set between two small windows and held together by a border of raised quoins.  Similar quoins frame the windows of the outer bays, and the top storey had them too.  A high hipped roof was pierced by two dormer windows.  The house looked very much like Barretstown (Kilkenny), and was on the cusp between the Dutch-inspired Beaulieu tradition and the 18th century Palladian classicism  that was reaching Ireland in the 1730s.

  1. There are some papers of the Auchmuty family in the Wiltshire and Swindon Archives. I have a digital copy of a lease to various tenants, includng my ancestor William Moffatt, from Arthur Auchmuty that is dated in 1696. That is the earliest document in the bundle, but there are later ones.

    1. Thank you for this reference, which I have now included in the blog post.
