‘Ciaras’ parents most likely weren't brought up in proper Sikhi, more Punjabi culture.
There are actually not as many people taking a letter to name their child any more- this is mostly because new parents now haven’t ever been educated with a reason as to why to do that.
Well you know maybe the parents of these children had a hard time at school and want to spare their children from that.
I went to a church of England High school there was like three Asians per year thats it you know how much crap I had to take. I'm not condoning having English names but I can understand why.
