Baiba is from the Latvian — possibly a folk hypocoristic of Barbara, with deep Baltic resonance. Baiba Strautmane — Latvian artist. Baiba Bērziņa — Latvian historical figure. Princess Baiba — Latvian heritage naming.
Baiba 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 Baiba reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
