Milda is from the Lithuanian Milda — mil (love, dear). Milda is the Lithuanian goddess of love + freedom + courtship in pre-Christian Baltic mythology — central to traditional Lithuanian + Latvian + Old Prussian pre-Christian heritage.
Milda 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 Milda reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
