Philipp Heinrich Appelhans, son of Johannes Rutger Appelhans & Anna Maria Schuster, was married in St. Lambertus Catholic Church in Bechtheim on 25 November 1738 to Anna Katharina Hueff, daughter of Johannes Georg & Anna Barbara Hueff. She was born ca. 1722 in Waldenbach (Bavaria?).
Philipp Heinrich and Anna Katharina arrived at Oranienbaum on 13 September 1766 along with three of their children, all of whom had been baptized in Bechtheim: Johann Nikolaus (baptized 3 September 1747), Johannes Peter (baptized 24 July 1750), and Maria Elisabeth (baptized 14 June 1754). Heinrich Appelhans died shortly after arriving in Russia and his widow married Johann Heinrich Kress. Johann Heinrich Kress and Anna Katharina Hueff arrived in Rothammel on 21 August 1767 along with Anna Katharina's children by her 1st husband. They are recorded there on the 1767 Census in Household No. 2.
The parish record in Bechtheim records the marriage of Philipp Heinrich Appelhans and Anna Katharina Hueff in Latin:
