Castelow History, Family Crest & Coats of Arms
- Origins Available:
The Castelow 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 Castelow, 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 Castelow was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they were granted lands by the Earl of Pembroke in the Anglo- Norman invasion of 1172.

Castelow migration to the United States +
Ireland went through one of the most devastating periods in its history with the arrival of the Great Potato Famine of the 1840s. Many also lost their lives from typhus, fever and dysentery. And poverty was the general rule as tenant farmers were often evicted because they could not pay the high rents. Emigration to North America gave hundreds of families a chance at a life where work, freedom, and land ownership were all possible. For those who made the long journey, it meant hope and survival. The Irish emigration to British North America and the United States opened up the gates of industry, commerce, education and the arts. Early immigration and passenger lists have shown many Irish people bearing the name Castelow:

The Castelow 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.
