I do think the variety of names used is greater today though as when I was at school it was literally just Sarah, Emma, Becky, Vicky, Nicky, Claire, Rach, Joanne, Jenny, Laura, Kate and boys were Steve, Paul, Andy, Chris, Mike, Mark and Dave ( I think all my friend's husbands have these names)!!! I think it is more normal to have an unusual name today even though a lot of names are still duplicated.
My name was and is really unusual (unless you live in Scandinavia), people seem a lot more accepting of unusual names these days I have noticed! Unless people are more polite as you get older of course!!!
