Wisdom is from the Old English wīsdōm — knowledge, learning, sound judgment. Saint Sophia of Rome — early Christian martyr; the Hagia Sophia (Holy Wisdom) in Istanbul, built 537 CE, is one of the most-architecturally-significant buildings in human history.
Wisdom 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 Wisdom reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
