Colonel Richmond Webb and his wife are buried in the east cloister of Westminster Abbey. The tablet to him, over the door into the Pyx Chamber, has now lost its inscription. A record had been made of it and it read:
Near this monument are interred the remains of Lieut. Colonel Richmond Webb who was born of a distinguish'd family of soldiers, served his King and country with honour, truth, humanity and bravery. He was the best of fathers, most affectionate of husbands, and most amiable of men: he was sensible, modest, kind and good, and united the softest heart with the strongest mind. He departed this life on the 27th May 1785, aged 70 years. In the same grave are deposited the remains of Sarah his inconsolable window, who only surviv'd his melancholy loss four years, and died on the 8th June 1789 aged 66 years. She was the tender, faithful and worthy partner of his distinguish'd virtues. In all goodness they were truly one!
He was the only son of Richmond Webb, captain in the Guards, descended from the family of Richmond alias Webb of Wiltshire, and his wife Anne. Sarah was the daughter of J. Griffyths. Their children were Sarah who married Peter Moore, Richmond, Charlotte, Augusta who married Thomas Evans, and Amelia who married W.M. Thackeray and was grandmother of the famous author of that name.
