Titanic

I am looking for list of ships that left from Southhampton following the Titanic. An ancestor of mine told the story of standing on the dock and crying because the money he needed for passage on the Titanic hadn't arrived, so he couldn't go. Probably lucky for him since the majority of people drown. I can't find him in any of the genealogy seaches. I thought I could figure out how to search the passenger list if I could find which ships left within a month or so of the Titanic. If someone has further ideas I would appreciate your help. Thank You
