Colonel Sir William Robe (18 February 1765 – 5 November 1820) KCB KCH was a British Army officer of the Royal Artillery who served in the Revolutionary and Napoleonic Wars.

He was praised as an artillery commander in combat and an organiser of military operations, as well as starting the first regimental school for soldiers' children, and serving as the architect of Quebec's Anglican cathedral.

[2] Robe was promoted to be captain-lieutenant on 9 September 1794, and was appointed quartermaster in the Royal Artillery's 1st Battalion at Woolwich on 25 November, remaining there for nearly five years.

Having considerable knowledge of architecture and drawing, he was employed to design and to superintend the erection of the Cathedral of the Holy Trinity, which remains a permanent record of his talent.

He was in the advance into Spain against Joseph Buonaparte, the Battle of Talavera on 27 July 1809, and in the subsequent retreat over the Mesa d'Ibor to Truxillo, and thence to Badajos.

In 1810 he was appointed to the command of the Royal Artillery driver corps, and he took part in the retreat to the Lines of Torres Vedras, including the Battle of Bussaco on 28 September.

In August he returned to England on account of his health, but rejoined the army before Badajos on 20 April 1812, the morning after the capture of the Picurina Fort.

He commanded the Royal Artillery at the entry of the army into Madrid, at the surrender of the Retiro, and at the unsuccessful Siege of Burgos, when for the third time he was mentioned in despatches.

Their eldest son, William Livingstone, was born in 1791, and served alongside his father in the Peninsular War before dying at the Battle of Waterloo in 1815.

The fifth son, George Mountain Sewell (1802–1825), was a lieutenant in the 26th Bengal Native Infantry, served as adjutant in the First Burmese War, and died on passage to Chittagong.

She presented to the Royal Artillery Institution at Woolwich all the medals, orders, and decorations of her father and eldest brother, together with miniature portraits of each of them.
