There wasn't as much variation in names in the 80s and 90s though CorusKate I think every girl everywhere was called Amy, Becky and Sarah! (oh, and Emma and Laura)
I work in a pretty posh private school and have taught a huge range of names, some expected and some not.
Over the past 8 years I have taught 1 or more of the following:
Anastasia, Annabelle, Chantelle, Hugo, Sebastian, Riley, Hailie, Frederick, Georgina, Lara, Dylan, Montgomery, Maximilian, Cosmo, Jonquil, Athene, Gavin, Makayla, Juliette, Darren, Genevieve, Caprice, Fenella, Fabia, Tiffany, Orlando, Camilla, Athena, Lillie-Mae, Kia, Ptolemy, Antigone, Tia, Fitch, Katinka, Aurelia and Karizma.
Of course, those are just the ones often stereotyped. Most of the children are called Alfie, Harry, Thomas, Charlie, George, Jack, Chloe, Amelia, Olivia, Charlotte, Sophie and Ellie just like everywhere else!
