Rind is from the Old Norse Rindr — Norse goddess associated with winter and frozen earth. Rind is attested in Snorri Sturluson's Prose Edda (13th c.), Saxo Grammaticus's Gesta Danorum (c. 1200), and the Poetic Edda.
Rind 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 Rind reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
