My partner has a misspelled/misspelt name as well. The nurse who wrote the name down got it wrong. Never got changed though.
Mathew.
(Even funnier when his father admitted years later that he was just a little bit tipsy while filling out said paperwork. He'd been celebrating his newborn son, and was apparently still celebrating.)
It's caused my friend a lot of trouble, as he always gets asked why it's spelled that way.
