Kunnei is from the Yakut (Sakha) Күннэй (Kunnei) — Sakha feminine name from kun (sun) + -nei feminine suffix — sun-girl, daughter of the sun. Kunnei is one of the Yakut feminine names — central to traditional Sakha Indigenous Turkic-Siberian heritage.
Kunnei 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 Kunnei reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
