I know them. They are my Grandpa Coenen's 13 half brothers and sisters kids and familes. My Uncle Don Coenen is moving back to Harlan, Iowa this month. My Mom was Wilma Coenen Rogers. She had 5 sisters and 2 brothers. Charlie Coenen never married, Don Coenen had 3 girls. Now with new last names. I never really knew those half brothers and sisters families but once when my Mom was still alive we drove up to their family reunion! Their were 200 people there! Lots of Coenens, I'll ask my Aunt Marge Coenen Rosenthal she is still alive at 89 and she still remembers!
