I realised I could investigate by getting the system to bring up different versions of an intro I wrote. Among others I got:
His name was Neville Carter, and his Brother, Zoe Carter was dead.
Her name was Agatha Addison, and her Wife, Jacob Addison was dead.
His name was Ulysses Lam, and his Husband, Ananda Lam was dead.
His name was Konrad Goforth, and his Uncle, Agatha Goforth was dead.
Her name was Prudence Newsom, and her Sister, Jacob Newsom was dead.
Bug report's been sent.
