Regarding the article from the two sisters Berman/Knox who will visit Summerland later this year, I can advise that ancestry.ca returns many information sources for their grandfather, William J. Beattie who died in 1972 and is buried in Summerland.
His daughter Kitty married a Denike, and is also buried in Summerland.
William arrived in Canada in 1905 or 1907. In 1911 he is listed living with his brother-in-law David Thompson in Summerland. He was widowed with a two-year-old daughter.
