Derry until their estates were confiscated at the time of the plantation of Ulster; and (2) of a branch of the Ui Fiachrach in Co. Galway. A branch of the Derry family is said to have settled at an early period in Thomond. There are no doubt several distinct families of the name which is now a very common one all over Ireland.
