Little was heard of the Thebault family at the foot of Lake Koshkonong until towards spring, and the absence of the head of the Thebault family was noted.

The evidence

• “He was about the age of the young wife and probably gave her more attention than she received from the elder Thebault. Finally the winter of 1838-9 came on, the lake was frozen over and the marshes about the trader's quarters closed and very little was heard of the Thebault family till towards spring. The absence of the head of the Thebault family was noted, as no one seemed to know his whereabouts.”
