Tindra is from the Swedish tindra — to twinkle or sparkle (as stars do). Tindra Renvinge — Swedish historical figure. Tindra Hansson — modern Swedish dancer. Tindra Eklund — Swedish dressage rider. Tindra (Swedish folklore) — appears in some regional Swedish fairy tales as a star-spirit; the word is connected to the broader Nordic tradition of stjärnor (stars) being seen as souls or messengers in pre-Christian Norse cosmology.
Tindra 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 Tindra reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
