Bertha died of cancer in 1921 at the age of 41 and Charles re-married a Violet BROWN in 1930.
Charles Jr. went on to marry Dorothy Mable CLARK (1896-1960) and they had two daughters who had families that I am in touch with today.
Sydney went on to marry Alfreda May FRY (no dates) and also had two daughters, Barbara (1927-1977) and Norma (1931-1978). Norma never married but Barbara married a Canadian serviceman, Haig MONTGOMERY (1919-1981), whom she met during WWII and moved to Canada where she had four children.
