Happy Birthday, Ulster County! Ulster County Clerk Nina Postupack invites the public to celebrate with us! Founded on November 1, 1683, Ulster County was one of the original twelve counties in the province of New York. Staff from the Ulster County Clerk’s Archives division will have special artifacts on display and will be available to discuss local history questions and talk about resources and research tools the County Clerk’s Office offers those looking to learn more about our rich history. Join us for a special birthday cake, which will be served at noon during the celebration.
