Suz is of Latin origin and signifies 'lily'. It's a variant of Susan, which means 'lotus' or 'lily', both symbols of purity and beauty. This name was popular during the medieval period but has since become quite rare.
"The name Suz saw a significant increase in usage between 1947 and 1954, with eight births recorded that year compared to only five in the former. After this peak, it returned to its previous level in 1955. Overall, there were eighteen babies named Suz born over these three years."
