Based on my search of Czernowitz vital records (Sadagura was a district of it), I believe the parents are:
- Gerson or Gerschon Rothstein, died on April 20, 1893
- Brana or Breine Graf (or Greif)
The couple had other two children:
- Moses Leib, born in July 7, 1861
- Hersh born on August 4, 1859
According to the document, Simon was born around 1869. In his naturalization paper Simon declared his birth date as Dec. 10th, 1869.
