possibly dumb question...

Hey guys... I'm sorry if this has been asked a thousand times before. I checked the tags to make sure and didn't see it, but just in case I missed it, I felt I should apologize in advance. Anyway...

I've seen plastered all over google that Heenim's "official" English name is Casey, but no one ever mentions a source. I have never heard him or anyone else in/connected to SuJu say this (not saying proof isn't out there! if I knew everything, I wouldn't be asking questions. I just haven't seen/heard it myself yet). I've seen one vid where some other celeb was giving oppa and someone else English names he thought were appropriate for them, and the one he gave oppa was not Casey. (I can't remember what it was, sorry! ^^; I just know it wasn't Casey. I was actively listening because I thought it might be where it came from, but no go lol)

So my question is: Where on Earth did the name "Casey Kim" come from? Who first said it? Is it really his English name, or was it made up by a fan? (I think we all know how fast fan rumors can spread online >.>)

If anyone can help me, thanks in advance! =3 And if this isn't allowed or has been asked before, I'm sorry again.
