Rennard is an uncommon and unique given name of German origin, derived from the name Renardo which means 'wise' or 'powerful'. It was popularized during medieval times through various adaptations of the Arthurian legends, where Rennard appeared as a character in some versions of the story of Robin Hood. The name has since been associated with these historical narratives and has become synonymous with bravery, intelligence, and wisdom. Today, it is still considered an uncommon choice for a first name but continues to carry its rich historical significance.
Rennard seems to have been a popular name between the late 1950s and early 1980s, with peak years being 1953 (6 births) and 1971 (8 births). The name's popularity appears to have declined after the mid-1980s.
