According to the Historical View of Clinton County, Pennsylvania by "D. S. Maynard", Westport, Pennsylvania in Noyes Township was formerly known as Kettle Creek.^[1] This is also mentioned on The Clinton County Register & Recorders Office website and other sources.^[2][3]

The first settlement at the mouth of Kettle Creek was in 1785, when the land was a part of Pine Creek Township, Northumberland County, Pennsylvania.^[4]

The Kettle Creek post office was established circa 1847 or 1848, but was discontinued, leaving the present community of Westport without a Post Office for about a year. In 1850, a new post office was established, but the name Kettle Creek was already taken by a post office located at the head of the Creek, so the name "Westport" was already in use, hence the current name.^[4]

The first bridge that spanned the creek at Westport, was erected by Clinton County in 1852. The first railroad bridge, which was only a few feet away, was built in 1859. Both bridges were swept almost simultaneously by a flood on March 17, 1865, which caused severe damage. However, both bridges were eventually replaced.^[1]
