Widower Wihelm Grah, a leatherworker (Lederarbeiter), and his daughters (Christina, age 8; Katharina, age 7; Gertrude, age 5) are recorded on an appendix to the 1767 census of Beauregard in Household No. 46.
It is not known in which colony they settled.
The 1767 census records that Wilhelm Grah came from the German village of Arsalen [?].
There are no known surviving male lines of this Grah family among the Volga German colonies.
