I am with the ladies, I don’t think I would like to lose my last name unless it was ugly or impossible to spell over the phone. Not a fan of the dashed names, like you couldn’t make up your mind between the two names. You could change you name in court but that sounds like it’s more trouble than it’s worth. All that paperwork. Finally I didn’t think you could change your social security number. You can and SSA tracks the numbers internally.
