Baifern is from the Thai ใบเฟิร์น — bai (leaf) + fern (fern) — fern leaf. Pimchanok Luevisadpaibul (Baifern, ใบเฟิร์น, born 1992) is a Thai actress figure of 21st-century Thai cinema.
Baifern 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 Baifern reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
