I have been reading through some of the posts in this thread, and I would like to post my view on the Allisons and Nurse Alice Cleaver.
I do NOT place her at fault for the deaths of Hudson, Bess, and Lorraine. The fact that she ad " taken" Trevor was also a speculation. There are theories that the family had gone up together and that Alice and Trevor could have been separated from the rest in the confusion of the crowd. ( Separations were apparently not uncommon that night.)
Major Arthur Peuchen also quoted, " Mrs. Allison could have gotten away in perfect safety, but somebody told her Mr Allison was in a boat being lowered on the opposite side of the deck, and with her little daughter she rushed away from the boat. Apparently she reached the other side to find that Mr Allison was not there. Meanwhile our boat had put off."
It has also been said that Hudson brought Bess and Lorraine to Boat 6, and then walked off before the boat was launched. The Hudson's manservant George Swane was the only person who had known about Alice and Trevor, as he was the one who saw them off in Boat 11. The question remains if he ever found the rest of the Hudson's and informed them of Trevor's safety. If he did, it was indeed far too late for the rest of the family to save themselves.
Alice Cleaver had a duty. She was first and foremost Trevor's nurse and her job was to protect him, and she did just that. Because of her, Trevor lived. It was tragic that he was orphaned, though. But as we live today, I do not believe that we have the right to place blame on Alice for the death of her employers when we really were not there and do not know what happened to them.
