Although there seem to be plenty of people who know that Dives means 'rich', nobody yet has picked up that Lazarus is also an adjective prior to being taken as a personal name.
"Dives atque lazarus' could be translated as "The Rich Man and the Leper"
I don't know enough Hebrew to know if the same is true of Eleazer, though it would not surprise me, since there is a trace of the same word root there.
