The story

How Cosmos Township came to be

From Wikipedia’s history of Cosmos Township.

Read it all →

Cosmos Township was first settled by Daniel Jackman, from Maine, in 1867. On his arrival, until he could build his house, he lived in a tent and cooked on an open fire. He took up a homestead in section 26. He returned to Minneapolis the following spring, but immediately returned and built his home in the summer of 1868. In 1877, he made a trip to the Black Hills and spent the season in gold mining, but returned in the fall. When the township was organized, the first election was held at his house. He was elected the first chairman of the board of supervisors and held that office for three years.
