Mills’ full name is Hayley Catherine Rose Vivien Mills. The name “Hayley” had been passed down for several generations in her family. (Her mother, also an actress, was Mary Hayley Bell.)
The film gave the baby name Pollyanna a boost as well during the ’60s.
*Though people tend to pronounce “Hayley” and “Halley” the same way, the surname Halley is traditionally pronounced to rhyme with “valley.” According to a poll I’ve had up for over a decade now, Hayley is the third-most-popular spelling of the name; the most popular spelling is Hailey.
