Hamilton, William Alexander Louis Stephen, 12th Duke of
British, 1845 - 1895
Brandon, William Hamilton, 9th Duke of
Douglas, William Alexander Louis Stephen
The son of William Alexander Anthony Archibald, 11th Duke of Hamilton and 8th Duke of Brandon, by his wife, Princess Mary of Baden (youngest daughter of Charles Louis Frederick, reigning Grand Duke of Baden, and 3rd cousin of Emperor Napoleon III), William Alexander Louis Stephen Hamilton succeeded his father as Duke in 1863. On 10 December 1873, he married Lady Mary Montagu [d. 1934], an Officer of the Order of the British Empire and eldest daughter of the 7th Duke of Manchester. They had a daughter, Mary Louise. William served as a Colonel in the Royal Lanarkshire Militia, hon. Col. of the 3rd Battalion H.L.I, hon. Col. of the Yeomanry Cavalry, and was a Knight Marischal of Scotland. The discovery of coal and ores in the area of the family home, Hamilton Palace, "ruined the habitation whilst it enriched the estate," and thus the building was eventually stripped and demolished (Marillier, 1926). It devolved upon the 12th Duke to disperse the gigantic collection of treasures at Hamilton Palace, (many of which had been gathered by Alexander, 10th Duke of Hamilton, during long tours in Italy), which he did at auctions held in June and July of 1882. The family pictures which were left over formed a separate sale in 1919 under the 13th Duke. As he died without male issue, Sir William was succeeded in the duchies of Hamilton and Brandon by his kinsman, Alfred Douglas Hamilton.
