The Evergreen Bluff Mining Company near Mass City was incorporated in 1853. For John Petermann, late of Württemberg, Germany, the mine would play a role in an immigrant story.
John arrived in the Copper Country with his wife Elizabeth Marie and infant daughter Christina after residing for several years in New York. Other family members accompanied them to Michigan: in 1860 John, Elizabeth, and Christina were living with John's mother, Eve Barbara Petermann, his sister Fredricka (Petermann) Rehfus, Fredricka's husband John Rehfus, and John's father Caspar Rehfus in Ontonagon. It was not uncommon for extended families to make a home together. During the week, John and his brother Ferdinand boarded at the Charles Witt family home near Mass City, where they worked for the Evergreen Bluff mine.
