Mrs Attenborough was the wife of Mr Attenborough and the mother of Dusty Attenborough.
History
Mrs Attenborough's father refused to allow his daughter to marry anyone who was not a soldier. When Mrs Attenborough fell in love with Mr Attenborough, a journalist, her father was naturally vehemently opposed to the union.
After many arguments, her fiance and father eventually compromised: they could marry so long as they promised that their first son would join the Alliance military. (SL: 'The End of One Journey')
