How Hillsboro came to be

From Wikipedia’s history of Hillsboro.

The post office was established in 1829 as Hillsborough. It was named from the terrain.

In Cain township, at Hillsboro, the oldest church was the Methodist. The building was 30 by 36 feet, costing one thousand six hundred dollars. The society was formed there in 1870, with thirty-two members. The New Light doctrines were then being pressed on the minds of people in this section, and it was a long, hard struggle to maintain the new church, but finally it succeeded, and it had forty-two members in 1880, since which it has advanced.
