Of all the families that boarded the doomed ocean liner Titanic in 1912, only one-fourth arrived safely in New York together. Albert and Sylvia Caldwell and their ten-month old son, Alden, were one of those rare families. They were idealistic young Presbyterian missionaries from the American midwest and had set out for Siam (Thailand) in 1909. But Sylvia got sick and they left Siam for England. They were returning to New York on the Titanic.
