 By 1730, the population of the parish had grown substantially, and it was decided by the Virginia General Assembly to create a new parish, Hamilton, out of Overwharton to better serve the needs of the people.The church at Occoquan became the parish church of this new parish.In 1732 another split was made, and Truro Parish was formed; the church, now renamed "Pohick Church" in honor of its position along Pohick Creek, became the parish church for this new parish as well, being the only church then in the neighborhood.
