This post answered one of my long unanswered questions! For years I've seen Jonathan spelled with three 'a' or with two 'o' and also Olsen with two 'o' but I wasn't sure if there was a correct way of spelling or if there was some sort of anarchy in the names of the characters.
oh, and off topic:
I don't often get names wrong, but for years I had a complete brain block over 'definitely'. Without fail, I'd spell it definately.
My native language isn't english and I'm very prone to mistakes. That word is one of those I always mispell. I usually write definitively instead of definitely.
It's just closer to the way it's said at home (definitivamente)
