Isaacs
A patronymic surname meaning “son of Isaac,” ultimately from the Hebrew biblical name meaning “he laughs.”
The #2,422 most common surname in the United States (2010 Census) — about 1 in every 20,650 Americans shares it.
Etymology
Isaacs is an English surname built from the personal name Isaac with the patronymic ending -s, which often means “son of.” The underlying biblical name comes from Hebrew Yitzhak, traditionally explained as “he laughs” or “laughter.” In English sources, Isaacs is treated simply as a family-name form of Isaac rather than a separate root word.
History
19th-century surname dictionaries consistently list Isaacs as a variant or derivative of Isaac. It is especially common among families of Jewish origin in Britain and elsewhere, though it also appears in broader English-speaking records as a patronymic surname. Related forms such as Isaacson, Hicks, and Higgs were often grouped together by older writers as names descending from Isaac through nickname or dialect forms.

Fun fact
Older surname scholars sometimes linked a whole cluster of names — including Hicks and Higgs — to Isaac through medieval pet forms, not just Isaacs itself.
