Starting Sept. 30, 2014, Genealogy.com will be making a big change. GenForum
message boards, Family Tree Maker homepages, and the most popular articles
will be preserved in a read-only format, while several other features will
no longer be available, including member subscriptions and the Shop.
I checked the 1922 Farmers Atlas for Harrison Co. and found in Boyer Twp., EUGENE BARNUM, wife Sadie; children John A. and Susan L., Woodbine Iowa.
GEORGE E. BARNUM, wife Maud; children, Ruth A., Lillian, Ethel and Edward, living on farm owned by A.E. Barnum. I know this isn't DIETZ info but thought it might help you. Have you checked the Harrison Co. web page at Rootsweb? They have a lot of biographies, cemetery records, etc.
