Mara Thorson, citing Michael Liebermann, says he was born to Samuel Nothmann and Mathilde Cohn on 12.06.1814, whereas JRI-Poland records the birth of Salomon to Samuel Schaya Nothmann and Magdalena Kohn in Langendorf on 26.01.1815.

In July 1815 Samuel Schayer and his family moved within the Tost district. The JRI-Poland records of this move name his wife, Magdalena geb. Cohn, and children
1. Isaac;
2. Hirschel;
3. Salomon;
4. Rosel;
5. Jette.

The enumeration of the siblings suggests that they are arranged in age order; certainly the three brothers are in their correct order. There is no evidence that the sisters are listed last because of their gender: other entries on the same page list female names before male names. If we assume that Rosel and Jette were the most recent additions to the family, then - barring triplets - Salomon must have been born before 1815 and Rosel must have been a twin of either Salomon or Jette.
