My parents also gave us names with the same initials. It's a pain in the arse when it comes to mail.I remember years back (I think it was because a character on Eastenders had a child called it or something similar) it was the height of sophistication of the chavs of my age to name their daughters ‘Courtney Paris’!
I also used to work for Social Services on the Emergency Duty Team and we used to get some corkers in! There were plenty of girls called Shakira or Chardonnay and also there seemed to be a habit of some larger families (I shouldn’t judge but usually rough ones; I mean, it was the emergency social services team, we didn’t get many candidates for ‘Parent of the Year’!) to name all their children with the same letter, akin to the Kardashian’s but well, worse! There was one with all J’s and another with S’s, to the extent they’d actually alter names to fit the theme. So there was Shaleen, Sheryl, Sharlotte… and the list went on!
