I am researching the family of Glenn HELLEY born about 1918 in Columbia Cty, WI. His father was Harry (Herold) HELLEY who lived in Jackson Cty, WI for much of his life. The family story is that Herold's father's surname was OLSON but when he came to this country there were so many OLSON's he changed his name to HELLEY (HELLE?). I found a Hans OLSON b. abt 1844 with wife Olina b. abt 1851 on the 1880 census. There children are: Ole, Anna, Inger, Harold and Clarence. I think this might be the right family. Does anyone else know anything that might help me verify this information?
