Philipp Decker, a farmer, and his family immigrated to Denmark (Schleswig-Holstein) in 1762.
Philip Decker and Jacobina Esewein, daughter of Daniel & Magdalena Esewein, were married on 11 May 1762 in the Danish parish of Grossenwiehe.
They joined the migration to Russia, and settled in the Volga German colony of Balzer on 28 August 1765. Philipp Decker, his wife Jacobina, and children (Maria Katharina, age 2; Johannes, age 2-weeks) are recorded there on the 1767 census of Balzer in Household No. 7.
Jakob Decker, presumed son of Philipp, and his family are recorded on the 1798 census of Balzer in Household No. Bz043.
The Eichhorn research of the Danish records and the 1767 census record that Philipp Decker came from the German village of Zweibrücken in the Kurpfalz region.
