Hallett
Usually a surname built from the old given name Hal, with the diminutive ending -ett, meaning “little Hal” or “son of Hal.”
The #6,000 most common surname in the United States (2010 Census) — about 1 in every 53,873 Americans shares it.
Etymology
Most historical surname dictionaries treat Hallett as a diminutive of Hal, itself a short form of Henry or, more loosely, a pet form used in medieval English. The ending -ett is a small-form suffix, so the name would originally have meant something like “little Hal.” Some older writers also suggested a Norman French personal-name source, but the Hal/Henry explanation is the standard one.
History
The name appears in English records in several forms, including Hallet, Hallett, and Hallett, and was later carried to North America and other English-speaking regions. Because Hal was a very common medieval nickname, the surname could arise independently in more than one place. Modern bearers are found especially in England, the United States, Canada, and Australia.

Fun fact
A 19th-century etymologist glossed Hallett simply as “little Hal,” showing how directly many surname explanations were built from nickname forms.
