Ellsworth is a surname, originating in England prior to or around the 12th Century A.D. in the Cambridgeshire area. The name comes from as "Ellesworth" or possibly Elsworth, from the place-name (and family seat) which in turn was derived from the Old English name "Eli" and "worth", an Old English word for farm or homestead. Many spelling variants are known to exist, including Ellesworth, Elsworth, Ellsworth, Elisworth, Ellisworth, Elsworthy, etc. Ellsworth is by far the most common Americanized / "standard" spelling.
