The Costallo surname came to Ireland
with the Anglo- Norman invasion
of the 12th century. They were originally from the Norman family Nangles, or de Angulos, and descended in Ireland
from Gilbert de Nangle. Costello and associated variations come from the personal name
of a son of Gilbert, Oisdealbhach, whose name consists of the elements "os," which means "deer or fawn", and "dealbhadh," which means "in the form of" or "resembling." The Gaelic form of the surname Costallo, which predated the Anglicized version of the name, is Mac Oisdealbhaigh. This is the earliest recorded example of a Norman family assuming a Mac surname. The prefix O has sometimes been erroneously assumed.

The surname Costallo was first found in County Mayo

Migration of the Costallo family to the New World and Oceana
experienced a dramatic decrease in its population during the 19th century. This was in a great measure, a response to England's imperialistic policies. Hunger and disease took the lives of many Irish people and many more chose to leave their homeland to escape the horrific conditions. North America with its promise of work, freedom, and land was an extremely popular destination for Irish families
. For those families that survived the journey, all three of these things were often attained through much hard work and perseverance. Research into early immigration and passenger lists revealed many immigrants bearing the name Costallo:

The Costallo Motto
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Ne te quaesiveris extra
Motto Translation: Seek nothing beyond your sphere.
