Dalley, Dally, D'Aillie, Dailey, Daily, Alyea & variants with links to New Amsterdam, New Jersey, Virginia, England or France in particular. The surnames supposedly originated in the part of France called Alliacum by the Romans (hence D'Aillie) near the Somme River. Some were Huguenots and fled to England, Belgium, and eventually to what became the USA. The Dally, Dalley, and Alyea families were established in New Jersey by the mid-1700s, mostly in the northern counties. There are records of Dalleys in early Virginia as well.
