In 19th century Poland could you get a civil divorce? If you were divorced (at least a Jewish get), could you remarry and have a civil second marriage?
Also, Chaskel is not listed as father on the birth records of any of their children. The midwife is recorded instead. The children's last names are listed as Kac, not Grynszpan.
My assumptions are that Tsutel Kac couldn't get a civil divorce so she couldn't remarry. And/or that as a divorced person she couldn't remarry. Or both. But that she had a get and they had a religious marriage.
Thanks very much for any information you can provide.
