It's great to see the Inwersen surname finally posted.I am descended from Amelia Ingwersen who was born in Bredstedt, Schleswig-Holstein, Prussia in 1839.She married 1st John Endlich (they had three children), 2nd Henry Joseph (they had two children), and 3rd someone else.
Amelia's parents were Friedrich Emmerich Ingwersen and Maria Henriette Christiana Bulow (or Belloff).They were also from Prussia.
Friedrich and Maria had 6 children (or more) named: 1.Frando (b abt 1821) 2.Frederick Andrew (b 1824) 3.Emil Ludwig (b 12 Aug 1826) 4.Anna (b abt 1830) 5.Wilhelm F. (b 30 Jun 1833) 6.Amalia (b 18 Mar 1839)
Most of the family Americanized their names.
They immigrated in 1848 and lived in Winnebago County and elsewhere in Wisconsin.The chlildren spread out around the midwest.
