The Day arms were recorded in London, c. 1582.
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.
English heraldry allowed arms to be shared by all legitimate descendants of the original owner. These symbols were treated as personal property that moved through the generations to all children. While the eldest son kept the original design, other family members could use the same shield without needing to change it or register their own unique versions.
The surname Day has deep roots in England, where it emerged as a descriptive name long before the sixteenth century. It likely originated as a nickname for someone who worked during the daylight hours or perhaps as a shortened version of the Old English name Daeg. By the time records confirm the presence of the family in London in 1582, the name was already well-established across various social classes. During this period, London was a bustling center of trade and migration, and families named Day were often involved in the city’s growing merchant and craft guilds. These early ancestors lived through a time of significant cultural change, as the English language evolved and the city expanded rapidly. Because the name is tied to common daily life, it reflects the experiences of ordinary people who helped build the foundations of urban English society.

The Day arms were recorded in Kerry, c. 1841.
Kerry was mountain and coast country in the far south-west of Ireland. Its land was poor and held by a few families for a very long time, and long unbroken holding fills a register.
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.
The Ulster King of Arms granted coats of arms to individuals who proved their social standing and good character. These symbols were typically inherited by all legitimate descendants of the original holder. If a family branch wanted a unique look, they could apply for a specific change to their design through the office to ensure their identity remained distinct.
The history of the Day family in Ireland is deeply rooted in the rugged landscape of County Kerry. While the name Day is often associated with English origins, families bearing this surname established a significant presence in the southwest of Ireland by the early nineteenth century. By 1841, records confirm that members of the Day family were well-integrated into the local community, likely working as farmers or tradespeople during a period of great social change. These early settlers in Kerry often lived in rural parishes where they contributed to the local economy and social fabric. Their presence in the region suggests that the family had either migrated from Britain or descended from earlier settlers who moved to Ireland to manage land or pursue professional opportunities. Over time, the family became a permanent fixture in the Kerry region, adapting to the unique cultural and historical challenges of life in Ireland.
Old English word for day or dawn.
