Hi, I am looking for Zimmermans in Iowa. My grandmother Hallie Zimmerman and her family lived in Iowa. She was married to my grandfather William Heins. I have very little information on my grandparents. My grandfather William W. Heins did enlist in the military before WWI in Iowa. He did serve as an enlisted army private and saw active duty. Any information would be appreciated. Thank you for your help. Sincerely, Linda Chorpening
