Ashworth
A Lancashire place-name surname meaning “ash-tree enclosure or homestead.”
The #3,531 most common surname in the United States (2010 Census) — about 1 in every 30,521 Americans shares it.
Etymology
Ashworth is a habitational surname from a place in Lancashire. The name is generally understood as combining Old English elements for “ash tree” and a settlement or enclosure term, giving the sense of an ash-wood farm, enclosure, or homestead. Older writers sometimes grouped it with related local names like Askwith and Askwith, but the core idea is the same: a place named for ash trees.
History
The surname is especially associated with Lancashire and nearby districts, and it appears strongly in northern English records. In later centuries it spread more widely through internal migration and industrial-era movement, which helped make it familiar beyond its original locality. The name is well represented in English surname collections and census-style surname maps.
