Mihrimah is from the Persian mehr (sun) + māh (moon) — "sun and moon." A modern revival name in the broader vintage-Ottoman aesthetic. Mihrimah in modern Turkish naming — has experienced revival following the Magnificent Century TV phenomenon. Princess Mihrimah — modern Turkish royal heritage naming.
Mihrimah 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 Mihrimah reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
