Mehar is from the Punjabi mehar (ਮਿਹਰ — mercy, grace, blessing). Mehar Bhasin — modern Punjabi-American figure. Mehar Mittal — Punjabi-Indian-American figure. Princess Mehar — Punjabi-Sikh royal heritage naming.
Mehar 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 Mehar reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
