Johann Caspar Glockenhammer, son of Valentin and Maria Magdalena Glockenhammer, was born on 15 April 1721 in Hofheim. He married there on 10 January 1745 to Anna Barbara Gräser, daughter of Lorentz & Anna Maria Gräser. They have two known sons: Johannes (born in Hofheim on 29 May 1752) and Johann Adam (born in Hofheim on 19 Jul 1755).
This family arrived at the port in Oranienbaum on 6 August 1766 and continued on to settle in the colony of Kautz on 20 July 1767. They are recorded there in Household No. 14 on the 1767 Census of Kautz. Anna Barbara evidently died shortly after their arrival in Russia, because on that 1767 Census of Kautz, Johann Caspar is recorded with another wife, Maria Katharina, and her children from a previous marriage.
