Named in a testimonial to his son Isidor.

Caroline's surname is taken from marriage and death records relating to their assumed children, Aron, Hugo and Roeschen; these records all name the parents as Marcus Heppner and Carloine (or Karoline) Saloschin of Lissa. Aron's and Hugo's records give their place of birth as Jarotschin, which is where Isidor was born.

Described as a bakery owner in Hugo's marriage certificate and Roeschen's death certificate. His son Isidor is described as a master baker in his 1920 marriage certificate.

Isidor was still alive when Isidor married in 1920.
