Singh was born on 27 October 1871 at
Elveden Hall,
Suffolk, in
England. She was the second daughter of
Maharaja Duleep Singh and
Bamba Müller. She had an elder sister
Bamba Sofia Jindan (1869–1957), a younger sister
Sophia Alexandra (1876–1948), three brothers
Victor Albert Jay (1866–1918),
Frederick Victor (1868–1926), and Albert Edward Alexander (1879–1942), and two half-sisters
Pauline Alexandra (1887–1941) and
Ada Irene Beryl (1889–1926) by Duleep Singh's second marriage, to Ada Douglas Wetherill. Sophia was the best known of the sisters as she was an active suffragette. In 1886 her father attempted to move to India with his daughters but was prevented from entering India and forced to return from
Aden. Catherine and her sisters then stayed at Folkestone, at 21Clifton Street. Initially, Queen Victoria had desired to put them under the care of Lady Login but on the advice of the
India Office in London their care was entrusted to Arthur Oliphant and his wife; Oliphant's father had worked as an
equerry. It was during this period that the princess was introduced to Fräulein Lina Schäfer, a German teacher and governess from
Kassel who was twelve years her senior. The Princess then developed a deep and intimate bond with Schäfer that lasted until the latter's death. When the Nazis came to power, on the advice of Dr.Fritz Ratig, her neighbour and accountant, she left Germany in November 1937 after disposing of all her property and moved to England via Switzerland.
Death Catherine Singh died due to a
heart attack on 8November 1942 at
Penn. On the evening of her death she and her sister Sophia had attended a drama in the village, dined in Colehatch House, and retired for the night. The next morning, when the maid attending Singh found her room locked, she informed Sophia who rushed and broke open the door and found her sister dead. The doctor declared her death as due to heart failure. Sophia was inconsolable at her sister's death. She was the only relative who attended the cremation of Singh due to
World War II. In memory of her sister, Sophia renamed the Colehatch House "Hilden Hall", adding Catherine's middle name, and sealed the room where she had died. Her last surviving sister took her ashes to Germany so that they could be placed with Lina's remains. When Catherine Singh died she left a will dated 1935 in which she stated "I, Princess Catherine Hilda Duleep Singh desire to be cremated and the ashes buried at Elveden in Suffolk. I give my gold jewellery, my long pearl necklace and my wearing apparel to my sisters Princess Bamba Sofia Jindan Sutherland and Princess Sophia Alexandra Duleep Singh". In a
codicil she had also requested that a quarter of her ashes be "buried as near as possible to the coffin of my friend Fräulein Lina Schäfer at the Principal Cemetery at Kassel in Germany". However, there was no mention of a bank account and a vault in her name in a Swiss bank in
Zurich, which were revealed to the public many years later. ==Legacy in Swiss bank==
