How Arms Worked in England

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.

Origin & History of the Reilly Family in England

The family name Reilly originates from the Gaelic name Ó Raghallaigh, which translates to a descendant of Raghallach. This surname first emerged in the ancient kingdom of Breifne, located in what is now County Cavan, Ireland. By the early 17th century, members of the family began to move beyond their ancestral lands due to shifting political landscapes and economic pressures. Records confirm that individuals bearing the name were established in London by 1620, likely participating in the growing trade networks and urban migration that defined the era. These early settlers in England were part of a broader movement of Irish people seeking new opportunities in the capital city during the reign of King James I. Their presence in London during this time reflects the family’s transition from a localized Irish clan to a broader presence within the British Isles.
