Named on daughter Eva's death certificate, which gives her maiden name as Silbermann. However, the record of Eva's move from Kempciowitz to Zawada in 1819 in the company of her father, siblings and step-mother names her father's first wife as Haye Joseph; Joseph could be a patronym indicating that her father was Joseph Silbermann.

Named on son Jacob's marriage record as Haye geb. Salomon.
