Johann Heinrich Hasenpflug & Anna Regina Schmidt of Altenschlirf were married in Büdingen on 29 May 1766. From the way it is recorded, it is unclear whether it is only Anna Regina or both of them who are from Altenschlirf, south of Lauterbach. She was born about 1747.
They immigrated to Russia, but Johann Heinrich evidently died before reaching the Volga German colonies. Anna Regina arrived in Norka on 15 August 1767, and is recorded there on the 1767 Census in Household No. 144 as a widow.
There is also a Johannes Hasenpflug, age 18, orphaned son of the deceased Johannes Hasenpflug, recorded in Norka on the 1767 Census in Household No. 150 - living with the Johann Heinrich Döring family. His relationship to Anna Regina and her husband is unknown at this time.
The Hasenpflug surname does not appear to continue as it is not included in the 1798 Census of the Volga German colonies.
