Ocllo is from the Quechua word for "pure, sacred." Mama Ocllo was the legendary foundress of the Inca civilization in Andean tradition — sister-wife of Manco Cápac, the first Sapa Inca.
Ocllo 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 Ocllo reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
