They may have been good enough for legendary actor Gary Cooper and singing superstar Barbra Streisand , but it seems their Christian names are now no longer cool . It may be unimaginable that you won ’ t be able to call friends ‘ Gazza ’ and ‘ Babs ’ in the future , but according to latest research these once popular names are no longer being used for the next generation . According to OurBabyNamer.com the name Gary reached peak popularity in 1952 in the US , coming in at number nine on the baby names popularity list where there were 38,000 registered Garys . However , in 2013 , only 400 babies were thought good enough to be called Gary . Legendary actor Gary Cooper was the flag-bearer for his Christian name in the 1950s . In another name shocker , Nameberry.com revealed that Barbra , spelled in the same unique way as global superstar Streisand , was also out . Streisand made her unusually-spelled , condensed name famous in the 1960s , when it peaked at Number 511 , only to drop off in the Top 1000 in 1971 . To make matters worse the conventional spelling of Barbara , a Top 10 name for three decades , only just gets in the Top 1000 . So no matter how you spell it the name seems a goner . Barbra Streisand made her unusually-spelled , condensed name famous in the 1960s . Other names compiled by baby naming website Nameberry.com that look on the way out are Llewellyn as a boy 's name and Claudine for a girl . The popularity of the 2013 Coen Brothers film Inside Llewyn Davis obviously has not rubbed off on cinema-goers . A common name in Wales , with the distinctive Welsh double-l beginning , Llewellyn appeared on the US list for six decades . Bye bye Baby : The girl 's name Claudine is another one that has gone out of fashion . But despite its rich Welsh history , literary cred and quirky nicknames , Llewelyn does n't cut it any more . While Claudine , the feminisation of the ancient Roman name Claudius , ranked in the Top 1000 for first half of the 20th century , then rose to new heights in 1970 thanks to the popularity of singer Claudine Longet , only to fall off the charts in 1975 . Claudine along with most other once-popular -ine and -een-ending girls ' names are now generally out of favour . The once popular Welsh boy 's name Llewellyn is also out when it comes to babies ' names .
The likes of actor Gary Cooper made this Christian name cool in the 1950s . Barbra Streisand made her condensed first name famous in the 1970s . But even the conventional spelling of 'Barbara ' is no longer popular . Not even Coen Brothers film Inside Llewyn Davis can save the Welsh name . In fashion in the 1960s , Claudine is no longer a trendy name for a girl .
