The area that would become known as Sanilac County, was originally made part of St. Clair County. for judicial purposes. The area extended to Saginaw Bay and west to Tuscola County in 1848, the Legislature authorized the separate organization of the county and Lexington was the county seat until 1879 when it was moved to Sandusky.
In the Census of 1850, Sanilac Co. had three townships: Worth Lexington and Sanilac. Worth and Lexington Townships were close to the present size; Sanilac Twp. included the rest of the territory in Sanilac and Huron Counties.
The county was covered with forests and travel was difficult. A pioneer account from the HISTORY OF SANILAC COUNTY 1834-1984 p. 225 states Upon their arrival at the Fort (Ft. Gratiot) their packs were remade and only the absolute necessitates could be taken as the balance of the trip, a distance of about 24 miles, had to be made on foot. The balance of the belongings were left at the Fort to be picked up at a later date. There were no roads, only a trail made by the Indians through the woods. This story took place about 1842.
The names of this pioneer and his wife were David & Susanna Taylor McClure. The first settler was Joel Carrington who came into the area that is now know as Worth Twp. in 1834. Reuben Dimmon was 2nd settler and taught the first school just south of the Village of Lexington.
