Surname Deasy - Meaning and Origin

Deasy: What does the surname Deasy mean?

The last name Deasy is believed to be of Irish origin, and is derived from the Gaelic Ó Deasach, which translates to “of the south” or “one from the south.” It is also thought to originate from deas, meaning “right” or “proper” in Irish.

The name is most likely first found in County Galway, in the western part of the country, and is likely to have been borne by an ancient Gaelic family who were descended from a descendant of a powerful 10th-century Irish tribal chieftain.

The Deasy surname can also be found further afield, including in England and Wales. It is thought that this is because many Irish people emigrated from the country during the 19th century, mainly because of the potato famine and other injustices.

The Deasy family can be known for its assertiveness and determination, which is likely to have been passed down through the generations, considering the difficult times they have faced. This strong sense of courage and independence will no doubt be an asset in many areas of life, and will help them to always stand proud no matter what challenges come their way.

The last name Deasy is primarily found in Ireland today. The Irish spelling of the name is de Siún. It is believed to have descended from a tribe in medieval Ireland known as the Uí Días.
