Vijaya is from the Sanskrit vijaya (विजय — victory, conquest). Vijaya Lakshmi Pandit (Sarup Kumari Nehru, 1900-1990) was an Indian diplomat and politician — sister of India's first Prime Minister Jawaharlal Nehru and aunt of Prime Minister Indira Gandhi. Governor of Maharashtra (1962-1964).
Vijaya 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 Vijaya reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
