Inez is the Spanish form of Agnes — from the Greek hagnē (pure, holy). President, how long must women wait for liberty?" were directly quoted by suffragists picketing the White House.
Inez 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 Inez reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
