my theory is that the mother doesn't want the memories of her first born to be mixed up with the current duke that's why she forced him to change. For them, he's just a replacement and will very soon pass down the position, that's why the oldest kid's successorship training is so intense and he's so 'in your face' about being the next duke. that's why the mother thinks that love will complicate things, cause the duke might start to want the position for himself if he had a wife that's not willing to give up the position.
