Origins Available: Irish
The Irish name Dease is an Anglicized version of the Gaelic name Déiseach, which is thought to have originally been a nickname
for a member of the vassal community ( feudal
servants) called the Déis, a word of uncertain origin. There was also a Decies barony in County Waterford
, and in some cases, this name likely originated with a native of that barony.
Early Origins of the Dease family
The surname Dease was first found in counties Cork and Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland
in the province of Connacht
. It is thought that immigrants from Waterford
took on this name after they arrived in their new homelands. First recorded instance of the name appears to be a bearer of Dacy, who was a Drogheda juror in Cork as early as 1313. There is a legend in Cork that all the Deasys of the county are ancestors of a child who was rescued from a massacre in the barony of Decies in about 1620. It is claimed that he was then protected by the O'Donovans of the Island, and went on to have seven sons.
