(Correction) In 1920, the family is listed as SYPOSZ, at 1925 N 15th, St Louis, comprising Joseph and Victoria, plus three children: Joseph, Albert and Lucille. Also at this address is Anthony and Anna "SMITH" and children (Anthony and Helen), quite possibly Victoria's brother Antonio.
In 1930, the family is exactly the same people and house, but listed as SEPER, and the SMITH family no longer lives there.
