I'm new to the Jewishgen groups and I found this thread.
My great grandfather was Charles (or Kallman) Arndt born in Nakel in 1831.
He moved with his family to Liverpool sometime between 1876-1881.
I believe his first wife was Carolina Hirsh born 1830 in Wirsitz (modern day Wrysyzc).
They had a son, Herman b. 1857 in Nakel.
His second wife was Pauline (maiden name unknown, although possibly Schwartz) born 1833 in Colmar in Preussen (modern day Chodziez).
Simon b.1860 Colmar
Elias b. 1863 Colmar (my grandfather)
Ernest b.1864 Colmar
Max b.1866 Colmar
Dora b.1871 Nakel
Joseph b.1873 Nakel
Lena b.1876 Nakel.
So as you can see, my Arndt branch has strong links to Nakel and Posen in general and I wonder if our families are linked?
