I have read in a secondary source that on March 24, 1812, 45 heads of Jewish Langendorf families obtained their citizenship papers. Among these were 2 of my direct ancestors.
I have searched the JewishGen database [https://www.ancestry.com/search/collections/1509/], but unfortunately their names did not show up. Does anyone know how I can access records for the obtaining of citizenship in Langendorf for Jews in 1812?
Thank you very much indeed.
