In the early 20th century, boys names like William, John and James dominated the list of baby names, as they had for the last century, said Linda Rosenkrantz, co-founder of nameberry.com. "Tradition is everything," she said. "Boys were typically named for their fathers and other family members."

However, it was different for girls. "Even though Mary was still number one, as she would for another half century, parents widened their horizons," Rosenkrantz said. Along with saints and biblical names, new names such as Dorothy, Mildred and Gladys began to appear.

Famous women of the 1910s had an effect on baby names, said Rosenkrantz. Popular monikers included Marie (Curie, a Noble Prize-winning chemist) and Florence (Nightingale, the founder of modern nursing). Flower and gem names also gained popularity with Rose, Pearl and Ruby.

John was still the top name for boys as well as William, James, Robert and George. But in 1914, German-inspired names, such as Bertha, Carl, Gus, Rudolph, Herman, Otto and August declined because of the start of WWI.

The 1920s brought on big name changes, as pop culture icons influence names for the first time, said Rosenkrantz. For example, names like Gloria (Swanson), Jean (Harlow) and Myrna (Loy) began to gain popularity. Other female names on the rise in the 1920s included Dorothy, Doris, Mildred, Eleanor, Thelma and more. Additionally, the name Betty entered the Top 10 in the 1920s, the highest-ranking nickname used on its own.

According to Rosenkrantz, in 1924, Robert topped John, becoming the only non-Biblical name to ever hold the boys' top spot. Charles, Richard, Edward, Arthur, Harold and other boy names continued to rise in the 1920s.

The second most popular name in 1936 was Shirley, given to more than 35,000 girls that year, in honor of Shirley Temple. "The curly-haired beacon of bright optimism in the midst of the Great Depression influenced parents' baby name decisions," said Rosenkrantz. "Glamour" names such as Rita and Anita became popular during the Depression years, while Ronald and Donald joined Richard and Robert as nouveau classics, she said.

Rosenkrantz also said names like Patrick, Patricia, Maureen and Kathleen reflected the an influx of Irish immigrants during this decade.

The late 1940s marks the end of WWII with a new generation of names. After Dr. Benjamin Spock's book "The Common Sense Book of Baby and Child Care," which came out in 1946, encouraged parents to be relaxed and confident, and inspired dads to be more involved in baby naming. In 1947, the name Linda dethroned Mary for the No. 1 spot, said Rosenkrantz. "Actress Linda Darnell and a popular song by that name were major factors," she said.

The name Gary, as in Gary Cooper, peaked at No. 9 in 1954, according to Rosenkrantz. Irish names for boys were on the rise, such as Brian, Kevin, Ryan and Sean, and the popularity of TV westerns brought back old cowboy names, such as Cody, Jason, Jesse, Jeremy and Josh.

Pop culture was a big baby-naming influence in the 1960s. Scott, Todd, Duane/Dwayne and Bruce became popular after surfer dudes from "beach blanket" movies, said Rosenkrantz. Names sounding like nicknames, such as Tammy, Lori, Cindy and Terri, spiked in the early '60s after the 1959 release of the Barbie doll. " 'Kooky' names were born, such as Moon Unit and Dweezil, Frank Zappa's children's names, were on the rise," Rosenkrantz said.

Other influences included the British Invasion, which propelled the name Michelle, after the Beatles song. The name rose to No. 9 in the 1960s. "Unisex names, such as Terry, Tracy, Stacy, Jody, Casey and Kelly, as well as flower-child names like Sunshine, Leaf, Light, Rainbow and America emerged in the freewheeling, Woodstock/hippie days as gender stereotypes were being reevaluated," Rosenkrantz said.

Buoyed by Michael Jordan and Michael Jackson, the name Michael began its long reign in the No. 1 spot for boys.

The 1960s also saw a rise of black pride, with African-American naming patterns diverging from the general population as black parents looked to Muslim and African sources, said Rosenkrantz. "By 1973, 31 percent of African-American girls born in New York City would have unique names," she said.

Nicknames -- Johnny, Jimmy and Betty -- fell by the wayside as children were called by their full names -- John, James and Elizabeth.
