Please answer the following question: Found the following article online, use it to answer the question: What is the first name of the person who moved with her sister Winifred into a flat in Frognal Mansions, Hampstead on 24 December 1942? In 1937 Ferrier entered the Carlisle Festival open piano competition and, as a result of a small bet with her husband, also signed up for the singing contest. She easily won the piano trophy; in the singing finals she sang Roger Quilter's To Daisies, a performance which earned her the festival's top vocal award. To mark her double triumph in piano and voice, Ferrier was awarded a special rose bowl as champion of the festival.After her Carlisle victories, Ferrier began to receive offers of singing engagements. Her first appearance as a professional vocalist, in autumn 1937, was at a harvest festival celebration in the village church at Aspatria. She was paid one guinea.

At the 1939 Carlisle Festival, Ferrier sang Richard Strauss's song All Souls' Day, a performance which particularly impressed one of the adjudicators, J. E. Hutchinson, a music teacher with a considerable reputation. Ferrier became his pupil and, under his guidance, began to extend her repertoire to include works by Bach, Handel, Brahms and Elgar.When Albert Wilson joined the army in 1940, Ferrier reverted to her maiden name, having until then sung as 'Kathleen Wilson'. In December 1940 she appeared for the first time professionally as 'Kathleen Ferrier' in a performance of Handel's Messiah, under Hutchinson's direction. In early 1941 she successfully auditioned as a singer with the Council for the Encouragement of the Arts (CEMA), which provided concerts and other entertainments to military camps,...
