Kean
Kean is a surname with two main origins: a nickname meaning “keen, sharp” or a place-name link to St Keyne in Cornwall, and in Irish use it can also reflect a Mac Kean form meaning “son of Keen.”
The #7,543 most common surname in the United States (2010 Census) — about 1 in every 70,042 Americans shares it.
Etymology
English and Cornish sources point to at least two different explanations. In one line, Kean is a nickname surname from Middle English or Old English words for “keen,” meaning sharp, quick, or eager. In another, it is locative, from St Keyne in Cornwall, a parish named for the saint. Irish material also connects Mac Kean to a Gaelic patronymic meaning “son of Keen,” which explains some later Irish examples of the name.
History
Lower explicitly treats Kean as a form of Keen and also notes a Cornwall place-name source. Bardsley likewise lists Kean with spellings such as Keen, Keene, and Keane, again giving both a nickname and local origin. Harrison includes Mac Kean as an Irish form, showing that the surname could arise independently in Ireland as well as in England. The result is a name with several parallel origins rather than one single family line.

Fun fact
St Keyne in Cornwall is one of the few English parish names that became a surname source, and its spelling helped generate several surname forms, including Kean and Keene.
