Looks like we might have a match with your KENNING ancients.Have we exchanged info before?
This is our data:
1. Christian John Henry Charles KENNING (born 28 Mar 1850 in Mecklenburg, Germany; died 18 Apr 1926 in Renville Co., MN) married first Henrietta SCHRAAN (23 Apr 1850 - 12 May 1885) on 23 Sep 1869 in Chaska, MN, and then married second Louisa EHRENBERG (16 Oct 1866 - 5 Apr 1936) on 16 Sep 1885 in Chaska, MN.
2. His son Charles W. KENNING (born 4 May 1872 in Chaska, MN; died 24 Sep 1956) married Mary UNKNOWN. Their children are Lucille Marie, Stanley L., Charles Edward, Herbert L., Mary M., Julia C., Martin and George. They lived in Independence, ND and Harmony, Price Co., WI.
3. Charles W. KENNING also married Hannah BRANDEL (1871 - 1922). Their children are Arnold and Henry.
Christian John Henry Charles KENNING and Henrietta SCHRAAN are my wife's great-grandparents. We have three more generations of KENNING ancients of CJHC KENNING, back to Eggert KENNING born in about 1760.
If this fits with your ancients, let's exchange info.
