As a former secondary teacher I used to see "waves" of names which echoed what was on TV - Kylies and Jasons, to name but 2. And then there would be all the fantastic variations in spelling! Sharon/Sharron, Aaron/Aron, Chantal/Chantelle/Shontelle Kerry/Keri, Jonathan/Jonathon/Johnathon etc etc
I remember arranging to visit a -pupil- student on work experience who I assumed was a boy with an old-fashioned Biblical name - Elisha.
Yes, you've guessed it was a variation on "Alesha"which I suppose is a phonetic version of Alicia!!
I used to get frustrated at report writing time because if the little dear had been christened "Micheal", "Mathew" or (really) "Jacququeline" - that was how you had to spell it.
Oh for Pat, Ted, Bob, Sue, Janet and John!
