On May 10, 1899, Sam wrote in a letter, "We shall reach London May 31, by way of Bremen & the steamer “Lahn” to Southampton.
The reason we do not wish it to be known that we are going in order to put a daughter with Madame Marchesi, is because the former doesn’t wish her present teacher to find it out till the tragedy is accomplished. Therefore we are diligently explaining to all friends that it is my business that hurries us to England—the idea being that when it gets into the papers it shall get it right (meaning, with the music-lessons UNMENTIONED.)"
Dolmetsch (page 300) writes: "Jean's epilepsy, however, had not yielded to treatments in Vienna. In fact, her seizures were becoming more frequent. Her longest interval without an incident had shortened to six weeks, and in April and early May they sometimes came on as often as twice a day. Clemens had some information about an osteopath named Jonas Henrik Kellgren with a fashionable practice in Belgravia (in London) and an even more flourishing sanatorium in his native Sweden. Kellgren’s kneadings, pommelings, and aerobics, called the “Swedish Movements Cure,” were reported to be efficacious in cases of “non-hereditary” epilepsy. Why not give Kellgren a try?"
June 2, 1899, The Clemens family made a sudden move to the Grand Hotel in Broadstairs, England, about two hours from London. The family returned to London June 9th.
July 87, 1899, the Clemens family left London by ship and traveled to Götenburg, Sweden, likely an overnight trip. The family’s accommodations in Gotenburg are not known. They were on their way to Sanna, Sweden, where Dr. Kellgren ran a summer sanitarium for his osteopathic treatment. Jean Clemens would undergo osteopathy for what would later be diagnosed as epilepsy. Clara Clemens remained in London and would rejoin the family in Sanna later in the month.
September 29, 1899 Friday – The Clemens family left Götenburg by ship to London. They stayed at the Queen Anne Residential Mansions & hotel, London
October 6 Friday – A bill was given to Sam from Queen Anne Residential Mansions & hotel for this date in the amount of £25.11.8 for the period Sept. 30 to Oct. 6; it was paid on Oct. 12 [1899 Financial file MTP]. Note: there is no other bill in the files for the Queen Anne; it is assumed they moved after this day to 30 Wellington Court (Albert Gate).
The family relocated to Dollis Hill, July 2, 1900.
