Johann Wilhelm Lung and his brother Georg Heinrich are recorded on the 1798 census of Straub in Household No. Sr11.
Johann Philipp Lenk [believed to be Lung], a clerk (Schreiber), and his wife Maria Barbara are recorded on the 1767 census of Straub in Household No. 50. They had settled there on 19 August 1767.
The 1767 census records that Johann Philipp Lenk came from the German village of Fitegen [?] in the Hohenlohe region.
[This surname is translated as "Mong" on the 1798 census of Straub, but Lung confirmed in later generations.]
