I decided to do a quick search to see if there is anything new and I found that her mother had a brother Saul. He was a dentist and married Gertrude Rose in Cleveland, Ohio on 01 Jun 1928. After the marriage record, I found a 1920 census for him. He was living with his parents and siblings. Saul’s nickname was “Sollie”. Abraham Kanter emigrated from London, England to the USA in 1904. Abe was a tailor and born in Poland or Polish Russia (1910 & 1920 census lists two different places of birth, one Russia and the other Poland).
Of course I can’t stop with just this. Sarah Kanter Sampliner actually had 3 sisters and 2 brothers. I also found marriage records for Saul and Celia. Other sisters I have their last names from Abe’s obituary.
