The Kilby arms were recorded in England, c. 1620.
Arms such as these were typically recorded in York.
Yorkshire is the largest of the English counties, and it held more gentry families than any other. Land there was split among a great many households rather than a few, so a great many of them carried arms.
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 Kilby is of locative origin, meaning it was originally taken from a place name to identify where a person lived or came from. The name is derived from the Old Norse word "kil," meaning a narrow inlet or a wedge-shaped piece of land, combined with the Old Norse suffix "by," which refers to a farmstead or a village. By the year 1620, records confirm that members of the Kilby family were well-established in the historic city of York. During this period, York served as a major center for trade and administration in Northern England. Families living in the city at that time were often involved in the bustling merchant guilds or the local craft industries that defined the regional economy. As the family grew, they became part of the social fabric of Yorkshire, contributing to the local community through their work and civic participation.
Old Norse word for a spring or a small stream.
