My grandmother took the frankly courageous step of suing John through civil court. To my knowledge this was in theory both to have him recognise his paternity of my dad, and also to have him pay child support.
However, my dad thinks, and I still agree, that part of Olive still hoped that this would somehow make John come back to her, would keep him involved in her life.
She won the case, albeit with an insultingly low payout in terms of the child support John was required to give. 21/?
