Is Ellsworth Ma. named after Col. Ellsworth of th CivilWar ?

Answer 1

Ellsworth Maine
The town was finally incorporated by the Commonwealth of Massachusetts in 1800 as Ellsworth, named for Oliver Ellsworth, the Connecticut delegate to the 1787 National Convention that was then working on a Constitution for the new United States of America, and later the 3rd Chief Justice of the Supreme Court. (Oliver Ellsworth is thought to be the person who first suggested the name "United States of America" for the newly formed country.)
In 1869 Ellsworth was incorporated as a city by the Maine Legislature. The first City Hall was Hancock Hall, which stood at the corner of Main Street and School Street. It was destroyed by the Great Ellsworth Fire of 1933.
So the town has roots from France, England, Massachusetts, New Hampshire, and Maine but named after a delegate from Connecticut.

Answer 2

No. Ellsworth, Wisconsin is actually the place which is named after Col. Elmer E. Ellsworth of American Civil War.
