My Grandma's Story - Die with me

In 1920 my grandmother was attacked at St Arvan's, near Chepstow in Wales, by her "husband" of one day. She was hospitalised in Chepstow and her "husband" tried to kill himself following the attack. However, he was discovered by police, taken to hospital and did survive. Turned out he was a bigamist, with a wife and children in Chepstow. 9 months later my grandmother gave birth to a son. She already had a daughter with this man, who she met in Bath during the early WW1 years. Her daughter witnessed the attack in 1920. I have undertaken all the research into both families and I have put all the information down on paper together with numerous photographs and obtained the Service records of the man in question. There are also a number of stories about the daughter and my great grandmother included. I just need someone to put this into an order so it will flow properly.
