[1] Lord Archer died at Portman Square, Marylebone, London, in April 1778, aged 41, and was buried at the Church of St Mary Magdalene, Tanworth-in-Arden.
His son predeceased him and thus the peerage became extinct, but his properties (Umberslade, Pyrgo and a town house in London) were divided between his wife and daughters.
Umberslade eventually passed to Sarah, Countess of Plymouth, who married secondly William, 1st Earl Amherst.
Lady Archer moved to London with her daughters and living up to being a grand dame then became the subject of a series of malicious caricatures in the press.
She died at Charles Street, Grosvenor Square, London, in February 1801, aged 59.
