That makes sense,
My name is Kirsty-Lea and i often get not only Kristy but also Lee..... and many other variations are out there of spelling also.
but then my mum is Leanne and so the Lea is from her and I like it.

However I do like unusual names - and I wanted to call our daughter Yasmin however my husband doesn't like it and i didn't like jasmyn because it's fairly common, so i said well i am choosing how to spell it {and hoping to make it less common lol}
