Willus is of Latin origin and means "resolute protection". It is derived from the Latin word 'vellus', which refers to a fleece or woolen garment, symbolizing warmth and comfort. The name Willus was quite popular during the Middle Ages in Europe but has since become less common. It is associated with the Roman god Vulcan, who was the blacksmith of the gods and god of fire, metalworking, and craftsmanship. People named Willus are often known for their strength, resilience, and creative talents.
"Willus was a popular baby boy name from 1918 to 1930, with five babies named Willus born each year in 1918, 1919, and again in 1921. The name's popularity persisted until 1930, with another five births that year. In total, twenty boys were named Willus during this period."
