Old Lycoming Township is a township in Lycoming County that is actually older than the county. It was formed as part of Northumberland County on August 22, 1785, ten years before the formation of Lycoming County. The original boundaries of the township encompassed much of the territory that was previously governed by the Fair Play Men. The land between Lycoming and Pine creeks was outside of the legal boundaries of Pennsylvania until 1784 and the second Treaty of Fort Stanwix. The Fair Play Men operated a system of self-government from 1773 to 1785. Their claims to the land had no legal bearing in the state of Pennsylvania when it was finally legally part of the state. These men had some troubles gaining the title to the land that they had cleared and so long defended; ultimately, some obtained title to their lands, while others removed westward.
