Records, 1802-1884, of the American Fur Company at Mackinac Island; records of the collector of customs; records concerning history of Mackinac Island, Sault Ste. Marie, Chippewa County, and Mackinac County, including marriage records for Chippewa County, 1824-1870, minutes of Chippewa County Automobile Association, 1917-1930, and miscellaneous personal diaries.
The strength of the Sault Ste. Marie collection is the records of the American Fur Company at Port Mackinac. These records date as early as 1802 and include shipping documents from the Sault Ste. Marie area and nearby ports from 1802 to 1884. Among these documents are shipping manifests, clearance documents, bills of sale, enrolment bonds, Treasury Department circulars to custom collectors at the Port of Sault Ste. Marie and nearby ports, and personal and business correspondence.
Other portions of the collection are files maintained by Myron W. Scranton. Scranton was a son-law and business partner of Peter B. Barbeau.
