There is a story in my family about a cousin who had a child just after WW2 (the cousin is deceased and the child doesn't mind details being made public but they aren't necessary to this question).
The mother told everyone for the rest of her life that she had married the father, but only discovered that he had married her bigamously when the police turned up at her hospital bed to tell her the father had died in a motorcycle accident on his way to see his new child, and oh by the way there was another (previous) wife... Personally, I don't believe a word of it, but want to confirm or refute it with evidence.
How should I expect to find the reported marriage and subsequent events recorded? Would any changes have been made to the GRO indices for the marriage when bigamy was identified? And would this have been different if bigamy was identified prior to the death of the bigamous partner?
I will also search for newspaper reports of the fatal accident but don't expect any newspaper coverage of the bigamy as the bigamous individual was dead and thus a little hard to prosecute; if he had been alive when the problem was discovered, newspaper reports of the prosecution would be another angle to investigate.
