The story

How Theresa came to be

From Wikipedia’s history of Theresa.

Read it all →

The history of Theresa begins with the Native American cultures who lived in the area as early as 841 B.C. The first of the Native tribes to inhabit the town of Theresa was a group called the Meadowood Phase, who were early Woodland Indians according to the categorization of Dr. William A. Ritchie. This tribe is believed to be part of the early Adena culture and subsisted on hunting and gathering. Evidence of the tribe existing in the area was found at Muskellunge and Red lakes with finds of weapon points, nets, sinkers, and other various tools from needles to a beaver tooth wood scraper. Later, the Iroquois used the Theresa area as a hunting and fishing ground. Evidence supports that at one point the Iroquois had villages in the surrounding area and used the waterways of Theresa for trade and travel.

There is no Grange of the Patrons of Husbandry in Theresa, neither any agricultural society. The old society in Alexandria held its second (and last) fair at Theresa in 1839, and the present society in that town has its grounds — as are also the grounds of the Redwood Driving Park — just across the line in Theresa, though both are institutions pertaining especially to the village of Redwood, to which the grounds are immediately contiguous.
