Yeah it is with an L and I don't remember it either. I think I saw in an interview she took Peter(s) because of her grandfathers name being Peter or something like that. I know its got something to do with her grandfather, don't ask me what.
Also Douglas Sills' last name is really not Sills its a longer name like Sillverstein or something. I know he shortened it, I just don't know from what.
And hang on, when did you win the discus?
