I am researching a branch of my family, the Isherwoods, in 18th Cent London. They were "Ornamental Decorators to King George III" but the origins of the Company they operated on Ludgate Hill in the City of London appear to lie with a particularly talented Papier Mache Maker, Thomas Bromwich, who died in Highgate in 1787. Henry Isherwood, my 4x Great Granduncle, married Thomas Bromwich's niece, Ann Maria, and went on to run the business before passing it to my 3x Great Grandfather, Nicholas Isherwood. Apparently Thomas Bromwich's work compared favourably with French stucco work - Walpole and the poet, Thomas Gray, were both regular customers of his. Can anyone tell me more about this accomplished chap and his family?
