I am not sure if you were able to find any more information on Ella and Sarah Kanter. Ella married Morris Jacon Gitlin and living in Minnesota on the 1920 census and then in Columbus, Ohio on the 1930 and 1940 census. They had four children, Irving, Robert, Martin (Mickey) and Beldonna. Martin died in 1954, as I was told from my mother by a disease prominent to Jewish people.
In 1920 Sarah and husband Abraham Gitlin are also in Minnesota with children, Benjamin and Joseph. Abraham died in Minnesota in 1934. Lists his father as Isaac Joseph Gitlin, mother Jennie.
