DUNDAS, OF BLAIR CASTLE.
ROBERT BRUCE *, the Laird of Clackmannan brother. This Robert Bruce, the Learned Crawford designs, in his notes of Buchanan's History, page 94, "of Airth ".
It is, moreover mentioned that when the storm at Court blew over, which had overwhelmed the Lord Livingston and so many of his friends, the survivors had their attainder removed; and their forfeiture reversed; and the heirs of such as had been executed, had there estates restored. Among others, ROBERT BRUCE, son and heir of Robert, of Airth, Obtained restitution.
ROBERT BRUCE, Who was living temp. James II. Descended from Sir Edward Bruce, acquired the estate of Airth.
On the tomb in Latin: Ex Roberti Brussii Scotarum Regis Filio secando progenito, Baron of Airthensi.
On the tomb appears this English inscription:-
Heer lyes a branch of Brusse"s noble stemn, Airths Baron, who's high worth did sote that name. Hollande his courage honoured, Spain did feare, The Sweeds in Fonen brought the trial deare. At last his Prince's service called him home, to die on the Thame's bank, and leave this tombe, to bear his name into posteritie. And make all brave men love his memorie.
• Crawford states in his notes, that Robert Bruce, of Airth, was the Laird of Clackmannan brother, but the family of Airth never considered themselves a cadet of the Bruce's of Clackmannan, nor have the family of Clackmannan any charter older than those of Airth to prove so. Perhaps it maybe worth mentioning that the Bruce's of Clackmannan got a charter of their lands from King David Bruce. Now the Bruce's of Airth lived at Airth at the time of King Robert Bruce, before David Bruce existed; which proves that the Bruce's of Clackmannan must be either of a different family, or a cadet of the house of Airth. The Bruce of Airth bore for supporters two naked savages.
