My ancestor Johanna* Maria Christina (Christiane) KERSTEN was born on December 31, 1798 in Neuplatendorf, now Kreis [county] Mansfelder Land, Saxony-Anhalt. Her parents were Gottlieb KERSTEN, labourer, and Christina née Lüder (Lueder). She was their first daughter and married on October 9, 1825 in Neuplatendorf Johann Friedrich Andreas* Jacob Oertel,a widower. At that time her parents had already passed away. She died on November 25, 1842 in Neuplatendorf and left her husband and 6 children. Andreas died in 1861 in the poorhouse of Neuplatendorf. Maybe that members of the KERSTEN family emigrated like so many from the Harz area. If there is any connection to the KERSTENs from that area let me know. Danke!
