The Radu arms were recorded in Tournaisis, c. 1737.
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.
In Belgium, a coat of arms is considered personal property that is passed down through the male line to legitimate descendants. Families often use the same shield design across generations to show their shared heritage. If a branch of the family wants to change the design, they must apply for an official update to their specific version of the arms.
The family name Radu has deep roots that connect to the historical region of Tournaisis, located in present-day Belgium. By the year 1737, records confirm that members of the family were already established within this area. The name itself is often associated with Slavic origins, where it functions as a short form of names containing the element "rad," which translates to "happy" or "willing." While the family was living in the French-speaking environment of Tournaisis during the eighteenth century, the name likely traveled across borders through trade routes or migration patterns common in Western Europe at the time. Families in this region often worked in agriculture or local crafts, and the presence of the Radu name in official documents from this period suggests they were integrated into the social and economic life of the local parishes. Over time, the family adapted to the linguistic traditions of the Tournaisis region while maintaining a name that reflects a much older linguistic heritage.
Slavic root meaning happy, willing, or joyful.
