Other sections of the town began to be settled. Gideon Seeley opened a road to the town’s southern border where Turner Fenner built a first saw mill. Shubael Hall and family traveled to the land which was christened Hall’s Corners until a later name change to Navarino. Nearby Cradleville became known for its’ manufacture of grain cradles and was populated by the Chafee family. Parley Howlett set up his homestead in the northwest corner of Onondaga Hill, which came to be known as Howlett Hill. The blue and gray limestone quarries of Split Rock attracted Irish immigrants who extracted the stone that was used in the construction of many notable buildings in the city of Syracuse. As the city grew in size Onondaga Castle a.k.a Rockwell Springs, later Nedrow, became a north/south route for travelers and city folk to traverse. 

The areas of the town known as Danforth and Brighton were annexed by the city of Syracuse in the late 1880s and Onondaga Valley, which was the “hollow”, became attached to Syracuse in 1927. The remaining part of the Town of Onondaga has remained intact since then.
