I am trying to find Port Huron immigration records for the Ole Torkildson family who arrived in Quebec on the S/S Moravian on 12 May 1880, traveling to Zumbrota Minnesota. Ole's naturalization papers indicate he entered the U.S. at Port Huron in May 1880. Thus he entered the U.S. some time between May 12-31. The family's last name is often misspelled as Forkelson. The information on-line leads me to believe that there are no immigration records from Port Huron prior to those in the St. Alban's list. Are there any immigration records from 1880 that may be stored in Port Huron, Canada, or another location that might be searched at that location?
