Strahan
A surname of Gaelic origin, most often treated as a form of Strachan or a related Irish name meaning “descendant of Sruthán.”
The #9,172 most common surname in the United States (2010 Census) — about 1 in every 86,751 Americans shares it.
Etymology
This surname is usually explained through Gaelic forms that were later Anglicized in several ways. One line of explanation in older scholarship connects it with Irish O'Srutháin, meaning “descendant of Sruthán,” a diminutive of sruth, understood in some sources as “poet” or “cleric.” Other authorities treat Strahan as closely related to, or a spelling variant of, Strachan, and some Irish and Scottish forms have become mixed in later records.
History
The name appears in British and Irish surname traditions with shifting spellings, especially in Scots and Irish records. Older surname dictionaries often place Strahan alongside Strachan, Strain, and related Anglicized forms, reflecting both regional pronunciation and clerical spelling variation. In modern usage it is relatively uncommon, including in North America.

Fun fact
Older reference works sometimes list Strahan and Strachan together so closely that the distinction between them can be hard to draw from surviving records alone.
