Gray is from the Old English grǣg (gray color) — historically a surname now used as a modern unisex given name. Macy Gray (born Natalie Renée McIntyre, 1967) — American R&B singer; her 1999 On How Life Is album sold 8+ million copies worldwide; "I Try" (1999) won the Grammy Award for Best Female Pop Vocal Performance (2001) and reached #5 on the Billboard Hot 100; her distinctive raspy voice has been compared to Billie Holiday and Janis Joplin. Fifty Shades of Grey — E.L. James trilogy (2011-2012) sold 165+ million copies worldwide. Gray Atkin — modern American TV chef.
Gray 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 Gray reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
