Who Put the Harry in Harry's Brook?

Since google's AI could not answer the question this morning, it seems time to get the word out as to how Harry's Brook got its name. Harry's Brook, for those unfamiliar, drains the eastern half of Princeton, emptying into the Millstone River portion of Carnegie Lake not far from Kingston. Even a relatively small brook has many origins. The main branch originates in Palmer Square, flowing in a concrete culvert under downtown Princeton until it daylights at Harrison Street. Another branch flows east from Princeton High School and the Princeton Shopping Center, with the cleanest tributary originating high on the ridge in Herrontown Woods.  

It was Maine-based mapmaker and internet sleuth extraordinaire Alison Carver who figured out how Harry's Brook got its name, in a free-ranging correspondence with me back in the Covid days of 2021. My original question to her had been "who put the Herring in Herrontown"--a related question whose answer remains elusive.

Harry, it turns out, was really a Henry. I first learned that Harry was a nickname for Henry while researching Henry Fine, the man who did so much to build Princeton's math and science departments in the early 20th century, including bringing Oswald Veblen to Princeton in 1905. Old Fine Hall, and the newer math building as well, were named in his honor. 

Alison sent me a series of maps that showed the evolution of the brook's name, 

from Greenland's Brook

to a combination, in which the outlet was called Greenland's Brook with one of the branches being called Harry's Brook,

to a map that shows the whole thing getting called Harry's Brook.

How far back does the name go? The first mention of Harry's Brook in newspapers dates back to 1878, but Harry goes back much farther than that. The Municipality of Princeton has a webpage entitled Historic Princeton that states:

"In 1683 a New Englander named Henry Greenland built a house on the highway which is believed to be the first by a European within the present municipal boundaries. He opened it as a "house of accommodation" or tavern. Portions of this house survive within the Gulick House at 1082 Princeton-Kingston Road."

Is there something of Harry in the name of the road that bordered his land, Herrontown Road? 

An email from Alison shows the spirit of inquiry:

"I did a little research … Harry was the first landowner in the area. He had about 400 acres, (about 2/3 of a square mile) part of which is now the Gulick Preserve … but the cool thing is that Herrontown Road runs along the north edge of it. So, I wonder if Herrontown Woods was named after the road? And how old that road is? If it’s really old, then maybe the road was Henrytown or Harrytown, something like that, and it got changed over the years … it has a gap in the middle of it which makes me think it must have been an old road, since maybe that part was a footpath or was let to grow over …

questions questions …"
