Gotami (गोतमी) is the feminine of Gotama. Kisa Gotami is the heroine of one of the most famous Buddhist parables — when her only son died, she begged the Buddha to restore him.
Mahapajapati Gotami was the Buddha's stepmother and aunt — the first Buddhist nun, founder of the bhikkhunī sangha.
Gotami 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 Gotami reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
