I think Collapsible D will remain as the most likely but it would be difficult to confirm one way or another. I think we have to take the poignant, almost lyrical farewell by Michel Navratil Sr to his children near Collapsible D that is described in many Titanic works with a large chunk of salt. Michel Jr is supposed to have remembered it - it is even mentioned in his ET bio - but that sounds way too mature and detailed for a boy who was then not yet 4 years old. The chances are that Michel Jr had a recollection of parting with his father and realizing that his mother Marcelle "helped" by adding on the poignant parts so that the boys would have a good feelings for their deceased father.
Philip Aks was the only named unidentified baby when the Carpathia was reached to my knowledge that we researchers know by name.
ET will not list a Titanic survivor to a particular lifeboat unless there is some certainty about it. If you look at the survivor list for Lifeboat #15 for example, there are 38 names at present; yet, the boat was absolutely full, perhaps even slightly overloaded according to some accounts. Many Scandinavian male survivors who have not been allocated a particular lifeboat could have been on #15. With the Navratil kids, no one on board appeared to know their identity; the only survivor who could have recognized them was Bertha Lehmann, but she'd left on Lifeboat #12.
It certainly is ! And a huge indispensable resource. They update it every few months so it's always worth checking back for any corrections or new sources added.
