_Siller Gun of Dumfries._--Can any of your readers tell me the history of the "Siller Gun of Dundee" [Dumfries], and give me an account of the annual shooting for it? O. L. R. G. [The Siller gun of Dumfries is a small silver tube, like the barrel of a pistol, but derives great importance from its being the gift of James VI., that monarch having ordained it as a prize to the best marksman among the corporations of Dumfries. The contest was, by royal authority, licensed to take place every year; but in consequence of the trouble and expense attending it, the custom has not been so frequently observed. Whenever the festival was appointed, the 4th of June, during the long reign of George III., was invariably chosen for that purpose, being his majesty's birthday. The institution itself may be regarded as a memorial of the _Waponshaw_, or showing of arms, the shooting at butts and bowmarks, and other military and gymnastic sports, introduced by our ancestors to keep alive, by competition and prizes, the martial ardour and heroic spirit of the people. In archery, the usual prize to the best shooter was a silver arrow: at Dumfries the contest was transferred to fire-arms. See the preface to the _Siller Gun_, a poem in five cantos, by John Mayne, 1836.] _Margery Trussell._--Margery, daughter and coheiress of Roger Trussell, of Macclesfield, married Edmund de Downes (of the old Cheshire family of Downes of Taxall, Shrigley, &c.) in the fourth year of Edward II. Query, What arms did she bear? and were the Trussells of Macclesfield of the same family as that which, in consequence of a marriage with an heiress of Mainwaring, settled at Warmineham, in the reign of Edward III., and whose heiress, in later times, married a De Vere, Earl of Oxford? W. SNEYD. Denton. [In the Harleian MS. 4031. fol. 170. is a long and curious pedigree of the Trussells and their intermarriage with the Mainwarings, in the person of Sir William Trussell, Lord of Cubbleston, with Maud, daughter and heiress of Sir Warren Mainwaring. The arms are: Argent a fret gu. bezante for Trussell. The same arms are found on the window of the church of Warmineham in Cheshire. These would consequently be the arms of Margery, daughter of Roger Trussell. The arms originally were: Argent a cross formee flory gu.; but changed on the marriage of Sir William Trussell of Mershton, co. Northampton, with Rose, daughter and heiress to William Pantolph, Lord of Cubbleston, who bore, Argent a fret gu. bezante.]
