The Bronsons took active roles in the development of their new home town. Judge Bronson prepared and sponsored the city charter for Palatka in the state legislature. He also petitioned that the town be made the county seat of Putnam County, Florida. Additionally, he donated the land for the county courthouse, where it still stands today. The Bronsons and their two daughters, Gertrude and Emma, were members of the St. Marks Church, of which Isaac Bronson was chairman and one of the first vestrymen.
