Hans Myhre Help!!!

My g grandfather came from somewhere in Norway. All I know is he came around 1888 or before. His name on his naturalization papers says Hans Myhre, but he changed it to Hans Meyer. He was a wood carver. Family history says he came over to work in the Norwegian Exhibition at the Columbian Exhibit at the Chicago Worlds Fair. He later moved to Two Rivers Wisconsin. He was born 6/2/1861. He married Mathilda Sundborg who was from sweden also working at the Fair. Could there be any records of people working at this exhibit?? Thanks for any help or suggestions finding him. Cheryl
