Jeanette is the French diminutive of Jeanne — from the Hebrew Yochanan ("God is gracious"). A lifelong pacifist; the only member of Congress to vote against US entry into both World War I (1917) and World War II (1941) — the latter vote was 388-1. Jeanette Winterson (born 1959) — British author; Oranges Are Not the Only Fruit (1985), Why Be Happy When You Could Be Normal? (2011); OBE. Jeanette Lee — "The Black Widow" pool champion. Jeanette Bouvier — Jackie Kennedy's middle name was Bouvier.
Jeanette 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 Jeanette reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
