or I should have added that Robert is William's father - if someone has access to 1861 or 1871 census for that part of Liverpool then that may resolve the issue - my own suspicion is that as the connection back to Quilliam of the Victory (who as far as I know had no known issue) was only made in the 1900 isue of Porcupine magazine then I suspect it was a misunderstanding based on the name
