Where the De Lacy Arms Were Recorded

Map of Ireland showing where the De Lacy arms are recorded

The De Lacy arms were recorded in Lincoln, c. 1172.

Lincolnshire was rich farming country, and its wealth was spread across many middling families. Households of that size bought land and took arms, and the county holds a large share of English names.

This is where the arms were entered in the register. Families often moved to other parts of the country, so the same name can turn up in more than one region.

How Arms Worked in Ireland

Origin & History of the De Lacy Family in Ireland

The De Lacy family name originates from the village of Lassy in the Calvados region of Normandy. Following the Norman Conquest of England in 1066, members of the family rose to prominence by serving the crown as loyal landholders and administrators. By 1172, historical records confirm that the family had established a significant presence in Lincoln, where they played an active role in the local governance and social structure of the city. This move to Lincoln allowed the family to expand their influence across the northern regions of England. Over time, the family became deeply embedded in the political landscape of the Middle Ages, often acting as trusted advisors to the monarchy. Their transition from Norman landowners to influential figures in English society highlights the rapid integration of continental families into the British administrative system during the twelfth century.
