Esra (إسراء) is from the Arabic isrāʾ (night journey) — referring to Prophet Muhammad's night journey to Jerusalem. A widely used Turkish feminine name.
Esra Bilgiç (born 1992) is the Turkish actress (Dirilis Ertugrul).
Esra 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 Esra reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
