In about 1855, a private Catholic girls school moved to Beaufort House.[3] In 1856, St Mary's Catholic Chapel was set up in its grounds, with a separate entrance for the public, and closed in 1870, when the school moved to Notting Hill.[1][3]
In 1901, Dr William Simpson Craig (1822-1893), the father of the psychiatrist Sir Maurice Craig and politician Norman Craig was living there, as was Norah Palmer Holroyd, an ancestor of Michael Holroyd.[6] From 1907 to 1920, Craig's son-in-law, Dr Macnamara (and his wife) lived there.[6]
The house is now home to Johnny Van Haeften, a British art dealer specialising in 16th and 17th century Dutch and Flemish Old Master paintings. Van Haeften now runs his business from a refurbished coach house in the grounds of Beaufort House.[7]
