I’m guessing he pulled it out of his behind, because he didn’t get those ideas from facts or reality. The town is nearly 300 hundred years old. There really are not a lot of “new” communities in one of the oldest settled areas of North America.

“The building that now houses Hawley School was built from donations to Newtown by Mary Elizabeth Hawley in 1921”
