National Grey Day is celebrated annually on April 3 to honor the surname Grey, which has origins linked to the Boernician tribe that once inhabited the border area between Scotland and England. The name is derived from the Gaelic word ‘Riabhach,’ meaning “gray,” and can be traced back to the village of Graye in Calvados. The surname Grey serves as both a nickname and a place name, with historical roots in the region. The first recorded individual with the surname in Northumberland was Anschatel Groy, who fought alongside William the Conqueror. The day serves as a reminder of the cultural legacy of Scots who migrated to the U.S., many of whom lost aspects of their heritage over time. Celebrations may include honoring Scottish ancestry and recognizing the contributions of those with the surname Grey.
