The story

How Ellsworth came to be

From Wikipedia’s history of Ellsworth.

Read it all →

The town was originally known as "Trecothick", after Barlow Trecothick, a Bostonian who moved to London. He was an alderman, a Member of Parliament (MP), and a Lord Mayor of the City of London. He had a country estate at Addington, London, now called Addington Palace.

The name of the town was changed to "Ellsworth" in 1802, in honor of Chief Justice Oliver Ellsworth.

The first census of the town, in 1800, reported 47 residents.
