Vilma is the Hungarian, Finnish, and Spanish short form of Wilhelmina — from the Old Germanic wil ("will, desire") + helm ("helmet, protection") — "resolute protector." A top-1000 US baby name in the early 20th century, especially in immigrant communities. Wilma is the English equivalent (already in the library). Vilma Lwoff-Parlaghy — Hungarian portrait painter.
Vilma does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Vilma reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
