Ambrose Remaley immigrated to America in 1749 aboard the ship Lydia. He held land warrants for several hundred acres in the area now known as Upper Slatington and Washington Township. Remaley settled in the area south of Washington Street and was the second principal landowner in Slatington. Slatington's first source of drinking water came from a Remaley-owned spring in the southwest corner of the borough. The family developed several of the first farms in northeastern Washington Township.
