Jemima (יְמִימָה) comes from the Hebrew word possibly meaning "dove" or "beautiful as the day." In the Book of Job, Jemima is one of Job's three daughters born after his restoration — described as the most beautiful women in the land.
Jemima is popular in the U.K. and Australia but rare in the U.S. (where the Aunt Jemima brand association reduced usage). The British actress Jemima Kirke (Girls) is a contemporary bearer.
Jemima 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 Jemima reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
