The Irish and English surname Dalton is of Norman origin. The name is an habitational name for someone from Autun (d’Autun) in Seine-et-Loire, France. The place name derives from the Latin form Augustodunum, a compound of the imperial name Augustus and the Gaulish element dun meaning “hill or fort’. The Dalton family settled in county Meath in the 13th Century. The early spelling of the name was D’Alton. The family became Hibernicized and moved west to county Clare. Today the name is found throughout Ireland with high numbers in counties Kilkenny and Limerick. The name is first recorded in the United States in 1635 when Philemon Dalton, a linen Weaver, arrived in Virginia.
