Mangan
An Irish surname usually understood as meaning “descendant of the hairy one,” though some bearers may come from other Irish family lines.
The #5,508 most common surname in the United States (2010 Census) — about 1 in every 48,891 Americans shares it.
Etymology
The most cited Irish derivation connects Mangan with Gaelic forms such as Mac Mongain or O’ Managain, built from mong, meaning “hair” or “mane,” plus a diminutive suffix. In that reading, the name originally meant something like “descendant of Mongan,” with Mongan glossed as “the hairy one.” Some 19th-century writers also tried to link it to other Irish forms or to Norman/English-looking spellings, so the surname may not have a single origin in every family line.
History
Mangan is well known as an Irish surname and appears in historical anglicized forms such as Mangin, Mangin, and Mangan. It is best known today through the Irish poet James Clarence Mangan (1803–1849), which helped keep the name visible in literary history. In some records, especially outside Ireland, the spelling may overlap with unrelated surnames or later spelling changes.

Fun fact
The old Irish root behind this surname is the same one that gives the word for “mane,” so the name was originally a nickname tied to hair or hirsuteness.
