Understood. But there are other possibilities, some of which need to be investigated. Among the least mentioned but IMO most interesting claim is reportedly in an unpublished letter written by Titanic survivor Orian Davidson stating that Robert Daniel was rescued in the same boat as herself and her mother, Lifeboat #3 and helped with the rowing. This is mentioned in the book On A Sea Of Glass, quoting the source as Peter Engberg-Klarstrom. The reason I find this interesting is because Orian Davidson was Charles Hays' daughter and as it says in the article above, one of the business connections that Daniel established on board the Titanic was with Hays. That creates a strong probability that Daniel met Charles hays family members that consisted of his wife, daughter and son-in-law. In other words, Orian Davidson was most likely familiar with Robert Daniel and is unlikely to have mistaken someone else for him.
I have also read that Trimmer Thomas Dillon claimed that when he jumped off the stern of the ship towards the end, Robert Daniel was with him. Since Dillon swam to and was pulled on board Lifeboat #4, some people have conjectured that Daniel too was similarly rescued on the same boat. But would a Trimmer who worked below decks be able to recognize a First Class passenger?
