Surname O'Lannan - Meaning and Origin

all surnames with 'O'

O'Lannan: What does the surname O'Lannan mean?

The last name O'Lannan is an Irish surname that can be translated to mean "descendant of Lannain". The word Lannan is derived from a first name Lann, an early Irish Gaelic masculine name meaning "Fierce Warrior". This name likely originated with a clan associated with the Ui Fiachrach dynasty, a powerful kingdom dating back to the 5th century located in the area of North Mayo and Sligo in Ireland.

From the 12th century onward, the Ui Fiachrach dynasty was divided into numerous branches, of which the O'Lannan family likely belonged to the Ui Fiachrach Muaidh sept, which was part of the Ui Fiachrach Aidhne branch of the Ui Fiachrach and was closely associated with the area of the Corrib River, located between Lough Corrib and Galway Bay.

Today, many O'Lannans are of Scots-Irish descent, meaning that their ancestors left Ireland and moved to Scotland in the 1600s after a series of wars and famines left many people in Ireland without a home. From there, some O'Lannans departed for the American colonies and eventually the United States, following in the footsteps of the millions of Irish that left their home in search of a better life.

Today, the O'Lannan name is widespread and regardless of background, offers a reminder of the resilience and strength of the Irish people, with O'Lannan meaning a proud descendant of a fierce warrior.
