Philipp Jakob Schlarf arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard a ship under the command of Skipper Hans Karholm along with the family of Philipp Peter Fey.
It is believed that Philipp Jakob (age 11) should be recorded as a Schlarf, and that he and his sisters who arrived in Oranienbaum with Jakob Fey were Jakob's stepchildren. They are recorded on the 1767 census in a list of Beauregard recruits (No. 22).
The 1798 census of Zürich records Philipp Jakob Schlarf and his family in Household No. Zr52.
