Nokomis is the Ojibwe-Algonquin word for "my grandmother," specifically maternal grandmother — used both as kinship term and personal name. In Algonquin and Ojibwe tradition, Nokomis is the moon-mother and grandmother figure who fell from the sky world and raised her grandson Manabozho (the trickster-creator).
Nokomis 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 Nokomis reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
