Violet Eliza Camelia Kum Fon [Golden Phoenix] Sew Hoy, was born on 6 July 1892 in Dunedin, the only daughter of Choie Sew Hoy and Eliza Prescott. Her father friend, the historian Dr Thomas Hocken, was her godfather. She was educated at St Hilda's College, an Anglican private school in Dunedin, where she became the Dux (the student with the highest marks).

Violet was noted for her charm and beauty and was an accomplished pianist. In 1911 she married John (Sonny) Trengrove, who was one of the founders of the Trengrove & Barton butcher business in Manse Street, and later owned the Grand Excelsior and European Hotels in Dunedin. They had two children Iris Margaret Trengrove (born 8 June 1912) and Audrey Lilian Trengrove (born 23 November 1914) before being divorced.

Violet then married Maitland William Hoggan (1900-1962) in 1922. They had two children, William Maitland Hoggan (born 5 September 1923) and Anita Nancy Hoggan (born 11 Sep 1927).

When Maitland Hoggan abandoned her, shortly after the birth of Nancy, Violet had to raise her children by herself, a major effort during the Great Depression of the 1930s but she ensured they were well looked after and educated. Her descendants include three doctors, a musician, and an RAF squadron-leader.

Violet died on 24 Feb 1972 in Christchurch, aged 79.
