On our trip to Minneapolis we visited the Science Museum, which currently featues the Titanic artifacts and display. It was quite an emotional experience... I found myself teary at several points. We were each given a boarding pass representing one of the passengers, and at the end of the tour we could check the list of survivors to see if we lived or died.
My Grandmother and 3 children came to Canada to join my Grandfather in April, 1912, and travelling on board the Titanic was one of the options she was given. I would guess that cost was what prohibited her, but there are other theories, such as a delay in departure of Titanic. In any case she came on another ship, but I have always been interested in that sad event.
