Biographical information:
Earliest known in this line. Tanhum (and likely all) were born in Klintsi, thought to be, possibly, the town of that name in the Ukraine. All went to St. Petersburg shortly before the revolution.
Based on that, the children may have been born on or before 1900. Giving a rough estimate for the father of, possibly, 1870.
