The influence? Singer Jackie DeShannon, whose biggest hit, “Put a Little Love in Your Heart,” peaked at #4 on Billboard‘s “Hot 100” chart in the summer of 1969.
But this wasn’t DeShannon’s first hit. She’d already seen success with the song “What the World Needs Now Is Love,” which had peaked at #7 in the summer of 1965.
So it seems that sudden trendiness of “Shannon” was the x-factor that prepared expectant parents to see more name-potential in “DeShannon” the second time around.
The singer’s birth name was Sharon Lee Myers. She went through various stage names before settling on “Jackie DeShannon.” “Jackie” was chosen because it was gender-neutral, while “DeShannon” was created out of two earlier ideas: “Dee,” which, by itself, made the full name too close to ones already in use (like Sandra Dee and Brenda Lee), and “de Shannon,” which was often written incorrectly.
DeShannon also had a successful career as a songwriter, working with performers like Jimmy Page and Marianne Faithfull. In 1982, she received the Grammy Award for Song of the Year for “Bette Davis Eyes,” which she had co-written with Donna Weiss. (The song was a 1981 hit for singer Kim Carnes.)
The word Sway popped up for the first time in the U.S. baby name data in 2001:
2003: 14 baby girls and 5 baby boys named Sway
2002: 12 baby girls named Sway
2001: 8 baby girls named Sway [debut]
For a long time I assumed the main influence was MTV personality Sway Calloway. But, while I still think Sway had an influence on male usage, I’ve since discovered a much better explanation for the 2001 debut as a female name.
One of the main characters in the 2000 car heist film Gone in 60 Seconds was mechanic-slash-bartender Sara “Sway” Wayland (played by Angelina Jolie). She was the love interest of protagonist Randall “Memphis” Raines (played by Nicolas Cage), who was tasked with stealing 50 specific, expensive cars inside of 72 hours.
The film didn’t get great reviews, but I do remember appreciating the fact that each of the 50 cars was assigned a feminine code-name:
Peaches Jackson was an actress who appeared in films from the 1910s to the 1930s. She was born in New York in 1913. Her birth name was Charlotte Jackson. Peaches was also a character played by actress May West in the film Every Day’s a Holiday (1937).

Portland Fancy was a character played by actress Juliet Brenon in the film The Street of Forgotten Men (1925). (Plus there’s radio actress Portland Hoffa was most active during the ’30s and ’40s.)
The cute name Tisa first appeared in the U.S. Social Security Administration’s baby name dataset in the late ’40s:
1951: 6 baby girls named Tisa
1950: 5 baby girls named Tisa
1949: 11 baby girls named Tisa
1948: 15 baby girls named Tisa [debut]
What gave the name a boost that year?
The long-forgotten movie My Girl Tisa, which was set in New York City in the early 1900s. It followed a Hungarian immigrant named Tisa Kepes (played by Lilli Palmer, herself a German immigrant) whose aim was to earn enough money to bring her father to the United States.
Leonard Maltin called the film “sincere but uninspiring.”
So is Tisa a legitimate Hungarian name? Good question. It doesn’t seem to be a traditional female name, but there’s a well-known river that runs through Hungary called the Tisza. So perhaps this one is a modern creation along the lines of the Irish name Shannon (inspired by the River Shannon).
The name Tisa saw its highest usage (and even popped into the top 1,000 for a year) in 1970, when Theresa Magdalena “Tisa” Farrow — sister of newly famous Mia Farrow — decided to try acting and appeared in her first film, the low-budget counter-culture drama Homer (1970).
