A group of historians recently believed he might was the fireman who was
transferred from lifeboat number 16 to lifeboat number 6.
Thomas, the renewal of this thread reminded me of the exchange we had about Crimmins last year. I re-read and thought about that linked entry about him in Bill Wormstedt's page and I think there is an intersting point made, which does suggest the possibility that Crimmins was indeed rescued in Lifeboat #16 and later transferred to Lifeboat #6. I meant to get back to you about it soon afterwards but somehow forgot at the time.
Did Lifeboat #16 pick-up a swimmer? There is not much evidence to support it, but it is believed that the McCoy sisters Agnes and Alice were placed in #16. Later Agnes McCoy gave an interview to the
New York Herald and claimed that Alice and she helped to rescue their brother Bernard McCoy out of the water, although her account seemed a bit far-fetched. But Bernard McCoy also survived and some people believe that he was also on Lifeboat #16.
That made me wonder if Bernard McCoy had managed to sneak into Lifeboat #16 and was hidden by his sisters. If the lifeboat did pick-up a swimmer afterwards, it could have been Crimmins and that would fit in with his claim that he was almost unconscious when he reached it. As to Crimmins' allusion to it being the "last" lifeboat, I think Bill Wormstedt was suggesting that he meant the boat that was last in the line of port lifeboats, which #16 certainly was. And the McCoy sisters later could have "substituted" Crimmins with their brother Bernard McCoy to cover-up the fact that he had snuck into the lifeboat unnoticed while it was still being loaded. I agree with Bill's assumption that the bedraggled Crimmins mistook
Molly Brown for Mrs Astor in the dark; Mrs Brown did confirm that she helped to cover the inadequately clad stoker who was transferred to her lifeboat with her stole.
The fireman was described by Mrs. Brown as having a Cockney accent
I am not sure how many times
Molly Brown had visited London, but I doubt if she could have recognized a Cockney accent in those surroundings. It is also possible that - like you suggest in post #11 above that she was listening to one of the
other firemen in the same lifeboat.
