Wera is of German origin, derived from the Old Germanic element 'wer' meaning 'man'. It is a unisex name, though it's more commonly used for females. The name Wera was popularized by Saint Wera, also known as Saint Gertrude the Great, who was a Benedictine nun and mystic in the 13th century. The name has also been associated with Queen Werinhera, a legendary queen of the East Franks in German mythology.
"Wera experienced two peaks of popularity during the early thirties, with five babies named her each in 1931 and 1935."
