Jamie is the English diminutive of James — from the Hebrew Yaʿaqov ("supplanter"). Lifetime ambassador of Children's Hospital Los Angeles. Jamie Pressly (born 1977) — My Name Is Earl Emmy. James Bond's female characters often nickname as Jamie.
Jamie 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 Jamie reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
