Johann Heinrich Jung, a farmer, and his wife Eva (age 26) are recorded on the 1767 census of Philippsfeld in Household No. 26 along with a note that they relocated to the colony of Näb in 1768.
In 1769, Georg Jung and his family moved from Philippsfeld to Zürich. This Georg is believed to be the same person of Johann Heinrich because Eva Elisabeth Steinroth (age 56), widow of an unnamed Jung, is recorded on the 1798 census of Zürich in Household No. Zr03 along with her son Wilhelm Jung and his family.
Johann Bernhard Jung is recorded on the 1798 census of Zürich in Household No. Zr48. He is also believed to be the son of Johann Heinrich & Eva Jung.
The 1767 census records that Johann Heinrich Jung came from the German village of Küchen bei Waldkappel.
