## History

The area was first settled by the William Saxton family in 1834, which was one year before Hillsdale County was officially organized in the Michigan Territory. Saxton was originally from Canandaigua, New York and moved to Michigan, first residing in Raisin Township in Lenawee County. He purchased 160 acres (65 ha) from the government, built his log cabin, and settled in the undeveloped region with his family. Other settlers and family members moved to the area in the next few years. By 1839, several families now lived in the area, and Woodbridge Township itself was established in 1840.
The community became known as Frontier when it was organized in 1851. It was named Frontier, as it was the last Michigan settlement before reaching the Ohio state line. In 1855, residents of the community built the Woodbridge Township Hall at a total cost of $260. A post office began operating here on January 30, 1857 with Benjamin Duealer serving as the first postmaster. The post office closed soon after on August 6, 1858 but was restored on November 9, 1861. The post office has remained in operation ever since, and the current post office was built in 1869. In an 1857 map of Hillsdale County, the Saxton and Duealer homesteads, among other families, can be seen in section 12 in the northeast portion of Woodbridge Township. Frontier developed as a station along the route between Amboy going north to Hillsdale.
The name Frontier appeared on an 1872 map of Woodbridge Township. By this time, Frontier's first settler, William Saxton, had left the area and moved to Iowa. By 1879, the community had a population of around 150 and contained two general stores, a sawmill, stave factory, and several small mechanic shops. An Independent Order of Odd Fellows lodge was built in Frontier in 1912. Originally served by neighboring fire departments, the township appropriated $10,000 to purchase the lot next to the township hall to build their own fire department in 1957. The fire department now serves areas of several neighboring townships. In 1975, the Woodbridge Township Hall was recognized by the Michigan Townships Association as the oldest operating township hall in the state.
