An educated man, William Jackson took over the reigns of his father's soap and candle making factory. He enjoyed great financial success in his life, as well as great political success. At the age of 49, he became a United States Congressman. While in the political sphere, he became associated with the anti-slavery movement. It was during this time that the Jackson Homestead was used as a stop for fleeing slaves who were traveling the Underground Railroad. William died in 1855, leaving his wife Mary and three of his daughter's to keep up the house.
Jackson family members lived in the house from 1809 when it was built, until 1932. At that time, the family rented out the house, until 1949 when it was donated to the town of Newton. Today, the Newton History Museum is open to the public at the old homestead. One can view paintings, manuscripts, historical artifacts and much more, including a cellar which may have been a hiding place for runaway slaves. The museum not only offers information about the history of the Jackson family and the historic home, but also the general history of the town of Newton.
