Hi Ben,
I'd love to put names to the faces standing in the background, such as the man doing something with his camera and others standing around him. Some of these people may well have been seeing passengers off, so putting names to their faces would be almost impossible. At the moment I have no suggestions for any of these people.
As for the acquaintance of all these people, this was pointed out to me by Craig, look on pg.106 of the Fr. Browne photo book, in the letter from Mrs. L. Odell, April 20, 1912:
"We have wondered so much whether the gentleman friend of the lady who came ashore with us at Queenstown is saved, as we do not know his name."
The saddest thing is that these letters have been lost in a fire. I had written to E. E. O'Donnell asking about the letters, and in his reply he informed me that these letters have been lost in a fire. He was away that night. The loss of the letters pales in comparison that the gentleman next door lost his life.
I don't think that the photo could be of anyone Cherbourg bound. If I'm correct the photo was taken in the morning of April 11, 1912, after which the only stop was Queenstown where Browne disembarked.
Another tidbit from Craig, although he originally believed the correct spelling may have been "Nicholls" it was actually "Nichols" so the cross channel list does have it correctly. Anyway, Craig knows the details so much more than I do, he's done some research into this.
Regards,
Daniel.
