I reckon she left Edward Haydon, went to London during the war, then emigrated (either straight to US or via a trip around post war France), where she married and started a new life. She may not even admit to being married before when she marries in the US (there is a death for an Edward John Haydon in Walsall in 1995 age 82), if that is him, there must either be a divorce,or the US marriage is bigamous but it might not be him)
