Not as closely related as the husband and wife in the last post, here we have armorial stained glass memorials to Robert Dennistoun, to James Dennistoun of Dennistoun, and to Alexander Dennistoun of Golfhill. I have not done the research to see how they are related, but they must be at least cousins to a greater or lesser degree. Based on the arms shown in the windows, I must believe that James is from the senior line, and that Robert and Alexander are cadets of that senior line.)
Though the arms are all differenced, they each bear the crest blazoned in Fairbairn's Crests as: In a hand an antique shield sable charged with a mullet argent (all three windows, however, show the mullet as or), and the first two have the same motto (the third has no motto in the window at all): Adversa virtute repello (I repel adversity with fortitude) (which sounds to me more than a bit like a spell that might be cast in Harry Potter. But maybe that's just me).
The first window, memorializing Robert Dennistoun, bears the legend:
Robert Dennistoun, merchant, was the son of James Dennistoun (d. 1796) , one of the leading American merchants, and during the latter part of his life resided in Glasgow, and his second wife, Mary Lyon. Robert married Anne Penelope Campbell, a daughter of Archibald Campbell of Jura, and they were the parents of James Robert Dennistoun ('Ruffy'; he got this nickname from his wearing a fringe or “ruff” of beard under his chin), and grandparents of Admiral Peel Dennistoun.
Robert was a partner in George & Robert Dennistoun & Co. of Glasgow until his death c. 1815. The firm of G & R Dennistoun is known to have been the mortgagees-in-possession of Wingfield and Belle Vue estates on St. Kitts in 1825. He was one of the prime movers behind the formation of the Glasgow West India Association in 1807.
Robert Dennistoun's arms are blazoned: Argent and bend sable between a unicorn's head erased gules horned or and a cross crosslet fitchy gules, on a canton argent a demi-lion azure.
His wife's paternal arms are blazoned: Quarterly: 1 and 4, Gyronny of eight sable and or [should be or and sable]; 2, Azure a boar's head couped or; 3, Argent a lymphad oars in action sable.
The second window, memorializing James Dennistoun, bears the legend:
I believe the current window has Mr. Dennistoun's date of death incorrect; all the records that I found on-line for him give a death date of 1855. I suspect that the date was worn in the original, and that the 5 became an 8 in error.
James Dennistoun of Dennistoun (1803-1855) was the son of James Dennistoun and Mary Ramsay Oswald. He received his education at the universities of Edinburgh and Glasgow, and became a member of the Faculty of Advocates in 1824. Having traveled abroad in 1825-26, in 1836 he again went abroad, and spent twelve years away from home, chiefly devoting himself to literary research and art. The winter generally found him at Rome, while the summers were given to journeys in Italy and Germany. He formed a collection of early Italian pictures, drawings, and medieval antiquities, with which he adorned his house in George Street, Edinburgh, his permanent home from 1847.
He was a magistrate and deputy-lieutenant for the county of Renfrew, and became a member of most of the societies formed for collecting materials for illustrating the history of Scotland.
His wife was Isabella Katherine Murray (1808-1864) was the daughter of James Wolfe Murray of Cringletie, Lord Cringletie, and Isabella Katherine Strange.
A bust of James Dennistoun of Dennistoun found in the frontispiece of the 1909 reprint of his three-volume work Memoirs of the Dukes of Urbino. (A tip of the hat and a hearty "thank you!" to my good friend and fellow heraldry enthusiast Margaret Sainte Claire of Glasgow for bringing this to my attention. All three volumes as well as another work by Mr. Dennistoun can be found at https://archive.org)
James Dennistoun of Dennistoun's arms are blazoned: Argent a bend sable.
His wife's paternal arms are blazoned, I believe: Or a fetterlock and on a chief azure three mullets argent.
The third window memorializing Alexander Dennistoun of Golfhill, bears the legend:
Alexander Dennistoun of Golfhill (1790-1874) married 1822 Eleanor Jane, daughter of John Thomson of Liverpool. He was educated at the University of Glasgow, and with his brother John, Jr. for many years took a leading interest in the business of the well-known firm of J. & A. Dennistoun (founded by their father in 1780). He was elected MP for Dumbarton in 1835, but only served one Parliament owing to ill health. In 1851 he commissioned this portrait of himself and his family:
The arms of Dennistoun of Golfhill were matriculated in 1865 and are blazoned: Per fess argent and ermine a bend sable between a unicorn's head erased and a cross crosslet fitchy gules.
