How interesting to meet you! (and your name too?) Gottlieb & Bertha's daughter Emma had a daughter Martha who had a son Cyril= my father.

I have a picture of the Hamburg passenger list page which I will gladly share with you if you email me: kentuckybe1le@juno.com
Also I have found a NY Times article regarding the crash, and an exhaustive (but interesting) article in a book about Canadian train wrecks. Details from the ensuing court case.
Looking forward to collaborating with you!
