Johann Phillip Gross, son of Jacob Gross from Steinberg, and Maria Catharina Bruner, daughter of Nicolaus Bruner from Steinberg, married in Hirzenhain on 17 February 1735. Amoung their children (both born in Steinberg) were Johann Jacob, born 26 March, baptized 27 March 1739; and Johannes, born 16 August, baptized 19 August 1742.
Johann Jacob Gross married Anna Catharina Schleuning from Steinberg on 11 May 1764. Anna Catharina Schleuning, daughter of Johann Heinrich Schleuning, was born on 13 December and baptized on 16 December 1742. Johann Jacob and Anna Catharina had one child, Johannes, born 14 March and baptized 17 March 1765.
Johannes Gross married Maria Elisabetha Hämel on 10 March 1766. Maria Elisabetha Hämel, daughter of Johannes Hämel and Anna Margaretha Schauermann, was born 17 March and baptized 20 March 1739.
Both couples arrived in Russia on 4 July 1766 and are recorded on the Schulz First Settlers List in Households #22 and #23. Stumpp states that, in addition to the two Gross sons, Johann Philipp Gross also travelled to Russia, along with his second wife, a daughter, and an uncle. It is unclear if these additional family members survived the trip to Russia, and if so, where they settled.
