Her obituary was reported in the Catholic Examiner:
Sister Therese-de-l’Infant-Jesus of the Missionary Sisters of the Immaculate Conception (Yvonne Gerin of Coaticook, Quebec, Canada), died of a heart attack in St. Teresa’s Hospital, Kowloon, on Wednesday, 21 December 1960, aged 63, having spent 43 years in Religious life and 21 years in the missions.
Sister Therese came to the Far East in 1939 and was in Kowloon till 1941. Having been interned in Stanley in the early days of the Japanese war, she was sent to Canton in 1942 and worked there till 1949, when, shortly before the beginning of the Communist expulsion of missionaries, she was sent to the Philippines. In 1957 she returned to Kowloon and remained there till her death.
Sister Therese was both an ardent catechist and an artist of exquisite and very delicate skill. She began the study of drawing and painting as a child of eleven and as a nun continued this study under renowned masters, attaining real distinction in her art. Almost her whole life was spent at this work, with the addition of catechetical work after her arrival in the missions.
She was the eldest daughter of a profoundly Catholic family of thirteen. Five of her sisters followed her into the Missionary Sisters of the Immaculate Conception and she is buried in St. Raphael’s Cemetery, Kowloon, beside her aunt, Sister Marie-de-Loyola, who was superior for many years of the Sisters in Kowloon and Canton.
