1. Dates are inconsistent. Benedict was unlikely a father at 13-14 y.o.
2. Benedict is a prominent figure and there is not record of this Meyer in any public source.
3. Benedict was an oncle to my grandmother Raissa Berg who was in contact with his only known 2 daughters, Natalia (1901-1976) and Anna (1903-?). I keep the postal correspondence of Natalia and Anna with my grandmother. No brother is ever mentioned.
David, may I suggest you make some additional research on your side to find where exactly to attach this Meyer ?
