The surname Ahearn is of Irish origin and is derived from the Gaelic name "Ó hEachthigheirn", which means descendant of Eachthighearn. Eachthighearn is composed of two elements: "each" meaning "horse" and "tighearna" meaning "lord" or "master", thus the name can be translated to "lord or master of horses". It is likely that the original bearers of the surname were skilled horsemen or had a connection to horses in some way. The O' before the surname signifies "descendant of" and was commonly used in Irish surnames until a law was enacted in the mid-19th century that required the anglicization or modification of many Gaelic names.
