Morris and Burne-Jones then spent time with one of the Firm's patrons, the wealthy George Howard, 9th Earl of Carlisle and his wife Rosalind, at their Medieval home in Naworth Castle, Cumberland. In July 1874, the Morris family then took Burne-Jones's two children with them on their holiday to Bruges, Belgium. However, by this point Morris's friendship with Rossetti had seriously eroded, and in July 1874 their acrimonious falling out led Rossetti to leave Kelmscott, with Morris's publisher F.S. Ellis taking his place. With the company's other partners drifting off to work on other projects, Morris decided to consolidate his own control of the Firm and become sole proprietor and manager. In March 1875, he paid £1000 each in compensation to Rossetti, Brown, and Marshall, although the other partners waived their claims to financial compensation. That month, the Firm was officially disbanded and replaced by Morris & Co, although Burne-Jones and Webb would continue to produce designs for it in future. This accomplished, he resigned his directorship of the Devon Great Consols, selling his remaining shares in the company.
