I have talked to members of my family in Liverpool England, and they have drawn the same information which I have in regard to William Murdoch, whom went down with the Titanic in 1912. He was married to a woman named Ada in which he had no children with. But being stationed out of Liverpool he went on to have seven children with an Elizabeth Crogent of Liverpool. Unfortunatley the childrenwere out of wedlock so there was never any marriage certificate to back it up. But all of the children have taken the Murdoch name. This would explain the "mystery woman" who burst into and disturbed the congressional hearings after the sinking, in which he was blamed at the time and held accountable.My father has the Murdochname on his birth certificatewith the correct spelling. I have yet to find any more substantial evidence to back my theory , if anyone out there has any information would you please let me know. Thanks.
