Unknown to the family, Bert is Abcynthia’s father. Her mother, now dead, had an affair with Bert, so when Abcynthias left the town to go to university, she thought that both her parents were dead. Some of the remaining old codgers had their suspicions, but it was a well kept secret ~ not least, because of Horace Hogg’s (Abby’s father) violent and unpredictable nature. Fred’s family, Idle and his mother, are new to the town, coming only because Fred married Abcynthia (from now on known for short as Abby because it’s a fucker to spell)
Abby’s mother, Hannah Hogg, died in somewhat suspicious circumstances shortly before the mines closed.
