Johann Tobias Lenz (son of Johannes Lenz) and Adelgunda Beckel (daughter of Johannes Beckel) married in Eckartsborn on 7 December 1747. The Schwickartshausen parish records report the baptisms of four children, all born in Eckartsborn: Johannes, born 26 March, baptized 28 March 1749; Johann Jacob, born 6 March, baptized 9 March 1751; Conrad, born 26 February, baptized 28 February 1756; and Elisabetha Margaretha, born 4 February, baptized 6 February 1761. The family arrived in Russia on 15 September 1766.
When the family settled in Walter (First Settler's List Family #79), Tobias is married to Katharina (surname unknown) and the family includes two additional children: Heinrich, age 13, and Elisabeth, age 10. The available evidence suggests that Katharina may be the widow of Friedrich Alles, and Heinrich and Elisabeth may be Friedrich Alles' children. The Alles family also arrived in Russia on 15 September 1766. There is no Alles family reported on the Walter First Settler's List. Heinrich Alles appears in the 1798 Census, married to Elisabetha Sommer, with a son named Johann Tobias (after his stepfather). Elisabeth Sommer's sister, Katharina, is married to Johann Jacob Lenz. These facts may be coincidental, but they suggest a close family connection between the Alles and Lenz families.
