By the end of World War I, Williams was a successful and established artist. During the War and the early 1920s, Williams painted a number of imaginative works with religious overtones, notably ''
The Devil's Daughter in 1917, The Triumph
in 1918, The Imprisoned Soul
of 1920 and The Menace
from 1925. In 1924 she completed a large painting The Care of Wounded Soldiers'' commissioned by
Sir William James Thomas, who appears in the painting. It was initially hung in the Mametz Wood Ward of Cardiff Royal Infirmary but moved to the main foyer in the 1970s. It depicts a ward where an injured soldier is being treated by Sister Mary Jones. Others in the painting are matron Montgomery Wilson, who had served in a Boer War field hospital, private BJ Davies, a Welsh soldier evacuated from the western front, and senior surgeon Lt-Col Philip Rees Griffiths. When the hospital closed, the painting was stored in poor conditions. It was later loaned to the Royal Military Academy at Sandhurst where it now hangs in Robertson Hall. By the mid-1920s Williams had decided to concentrate on portrait work. She received a steady stream of commissions and although based in London, painted the portraits of several generations of prominent Welsh families including several members of the Morgan family, owners of the Cardiff
department store, and of the Novello Davies family, including
Ivor Novello. In London she had a patron in
Lord Riddell, who sat for four portraits and obtained other commissions for her. Most notable of these was the large scale work, ''St Paul's Cathedral Thanksgiving Service'', shown at the Royal Academy in 1933 and painted to mark the re-opening of the Cathedral after five years of restoration work. This large group portrait included both
George V and
Queen Mary. Williams painted a further portrait of Queen Mary in 1938 for
St Thomas' Hospital and among her other royal commissions were portraits of
Princess Margaret, presented to South Africa by a businessman in 1937,
Prince Charles,
Princess Anne and at least five portraits of
Queen Elizabeth II, including one of her as a young Princess. Williams visited the United States at least five times during her life and in 1922 was commissioned to paint a near life-size portrait of President
Warren Harding. Other notable commissions included portraits of
Henry Ford,
Field Marshal Slim and the decorative scheme for the Cardiff home of Sir William James. ==References==
