Dolly Parton (born 1946) — American country music singer-songwriter, businesswoman, and philanthropist who has sold over 100 million records, won 11 Grammy Awards, and written over 3,000 songs including Jolene, I Will Always Love You (Whitney Houston's biggest hit), Coat of Many Colors, and 9 to 5. Her Dollywood theme park (opened 1986) is the largest employer in Sevier County, Tennessee. Imagination Library — her literacy program — has given over 200 million free books to children worldwide since 1995. Helped fund the Moderna COVID-19 vaccine with a $1 million donation in 2020. Inducted into the Songwriters Hall of Fame.
Subject of countless biographies and her memoir Dolly Parton, Songteller (2020).
Dolly 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 Dolly reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
