What Famous Couples Were On The Titanic?

I don't know about couples, but here's a list of famous people:

Famous, well, there was John Jacob Astor (multi-millionairre and hotel magnate), Isador Strauss (founder of Maceys Department Store), Archiebald Butt (aide de campe and friend of President Taft). Benjamin Guggenheim (banker and multi-millionairre), Bruce Ismay (Chairman of the White Star Line), Jacques Futrelle (author), Frank Millet (artist), W.T Stead (editor and spiritualist), Charles M Hays (railroad president), Daniel Marvin (head of a movie firm), Karl Behr (famous lawn tennis player), George Widener, The Countess of Rothes, and so forth, virtually everybody in first class was either famous or notorious in some way.
Courtesy of www.allatsea.co.za the most easily recognized was The Unsinkable Molly Brown. She wasn't a couple, either, but was famous for, among other things, talking the rest of the people in the full lifeboat into looking for more survivors.
