The parish register of the Lutheran church in Büdingen records the marriage on 9 April 1766 of Philip Rau from Salmünster and Margaretha Eckert from Spielberg. They joined the migration to Russia.
Philipp Rau, a farmer, and his wife Margaretha arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard a pink under the command of Lieutenant Moisey Davydov.
They settled in the Volga German colony of Huck on 17 August 1767 where they are recorded on the 1767 Census in Household No. 71.
The Oranienbaum passenger list records that Philipp Rau came from the German region of Pfalz. The 1767 census records that he came from the German region of Fulda.
