Chapple
A surname usually linked to a chapel or chaplain, and especially common in Cornwall and other English areas.
The #9,068 most common surname in the United States (2010 Census) — about 1 in every 85,667 Americans shares it.
Etymology
Chapple is generally treated as a spelling variant of Chapel or Chappell, with the same basic source: a word for a chapel, from Old French and ultimately Latin capella, meaning a small chapel or shrine. In surname use, it may have been given to someone who lived by a chapel, worked at one, or was otherwise associated with it. Some English forms may also overlap with names derived from chaplains or chapel-keepers, so the history is not always perfectly separable.
History
The surname is found in English records in several spellings, including Chappell and Chapple, and the 19th-century sources you provided link it with the chapel name family. It is particularly associated with the southwest of England, especially Cornwall, where the Cornish place-name record also shows it. In modern usage it survives as a relatively uncommon surname in Britain and the United States.
