Granddad's younger sisters were Evelyn and Margery. Evelyn's middle name, Edith, was probably inherited from her mother's younger sister, Edith Turner, who immigrated to BC from the UK, and married Richard Edward Steed, another British compatriot. Evelyn married Art Nursery and lived in the lower Mainland area of BC, where they raised a family. Evelyn died 4 April 1987 at age 74. Art outlived her, but I do not know his death date.
Margery married Hugh Phillip Sigismund and also raised a family in the lower Mainland. Hugh passed away on 24 June 1975 at age 63. I don't have Margery's death date, but will post once discovered.
This is a photo of Granddad and his sisters, likely taken in the 1950's:
