That's just stupid. Theres loads of horrible people out there each with a name. The op will never meet these supposedly horrible sauls so why does it matter to her? I know a right bitch called charlotte but i don't go on Charlotte threads going i know a really nasty Charlotte as though that should make a difference to the op.
Choice of name will not influence a childs personality one jot. Especially when the op will never meet them!
And no offence but your post is probably the least relevant because you like the saul you know but don't like his mum. What's that got to do with anything at all?!
