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. Together they emerged from Lake Titicaca to found the city of Cusco and the Inca civilization — she taught the Andean women to spin, weave, and farm.
Featured in Garcilaso de la Vega's Royal Commentaries of the Incas (1609).
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.
