Jenks
A short English surname that most likely began as a pet-form of John, meaning “son of John.”
The #4,782 most common surname in the United States (2010 Census) — about 1 in every 41,745 Americans shares it.
Etymology
Jenks is generally treated as a shortened or altered form of the medieval personal name Jenkin, ultimately from John. In this tradition, the surname means “son of John” or more loosely “descended from John.” Some 19th-century writers also suggested a link with an old word for an engineer or skilled craftsman, but the John derivation is the standard explanation.
History
The name appears in English surname lists alongside Jenkins and Jenkinson, all tied to the very common forename John. It is especially familiar in England and later in the United States, where it survives as a comparatively uncommon but established surname. Earlier lexicographers sometimes debated whether similar forms could reflect occupational origins, but Jenks itself was usually explained as a John-based family name.

From the historical record
“JENKINSON. See John. JENKS. See John. JENNER. Pott, in his " Die Personcn- uamen insbesondere die Familiennameu," (Leipzig, 1853), considers this name a cor- ruption of the classical Januarius; but I think the medieval giiwur, a craftsman, engineer, or clever workman, a much like- lier origin — a man of genius…”
