The history of the last name Sheehan

The surname Sheehan is of Irish origin, derived from the Gaelic personal name Siodhcháin, meaning "peaceful." It first appeared in the Munster region of Ireland, particularly in County Cork and County Kerry.

The name can be traced back to the 12th century, when it was recorded as O'Sheehan, indicating a patronymic surname meaning "descendant of Sheehan." The prefix "O'" denoted a grandson or descendant in the Irish naming system.

In ancient Irish manuscripts, the name appears as O'Siocháin, O'Shehyn, and O'Sheehan. These variations emerged due to the challenges of transliterating Gaelic names into English during the anglicization of Irish surnames in the 16th and 17th centuries.

One of the earliest recorded instances of the name can be found in the Annals of Inisfallen, a chronicle of medieval Irish history, where it mentions an O'Sheehan chieftain named Donnchadh O'Siocháin in the year 1172.
