How Demi became Demi Moore
Demi Guynes took her surname from her stepfather, Dan Guynes; her biological father, Charles Harmon, left before she was born. Some references give her first name as Demetria, but Wikipedia records it as Demi, so we use Demi Gene Guynes here.
She began using the name Moore while dating the singer Freddy Moore, before their wedding. Sources differ on the date of the marriage (Wikipedia says February 1981; Encyclopedia.com says 1980). They divorced in the mid-1980s, but by then her career was under way as Demi Moore and she kept the name.
