Vera,
Are you still looking for Kleinendorst connections? You have some of your facts wrong in your posting.... Cornelius Kleinendorst 3-10-1851 in the Netherlands and married Jane Ver Huel on 12-14-1874 in Marion Co., Iowa. Cornelius died in 1934 not 1943 though.
My family line comes through Cornelius' brother, Teunis.
Many of the Kleinendorst family settled around Jasper & Marion Co., Iowa which is where I'm from.
Can we share info?
