Michigan borders four of the five Great Lakes: Michigan, Huron, Erie, and Superior. My ancestors lived in cities on Lake Michigan and Lake Superior, some of them even earning a living on the Great Lakes. My maternal grandfather, Otto August Fredrick, sailed the Great Lakes for 14 years. He was born in Manistee County, Michigan on 1 November 1878 to Johann August Fredrick and Louise Fredricke Zastrow. He died in Brethren, Manistee, Michigan on 5 Feb 1968 at the age of 89. To learn more about shipping on the Great Lakes check out this website.
