Vipsania (33 BCE-20 CE) was the daughter of Marcus Agrippa — Tiberius's first and beloved wife. Tiberius is said to have continued to love Vipsania for the rest of his life — when he saw her on the street, he is said to have wept openly.
Featured in Robert Graves's I, Claudius.
Vipsania 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 Vipsania reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
