I suggest you attempt to locate a translator of Sindarin (not The Grey Company, though. Their Elvish is fake). Then, just type in words you want your name to mean. Hobbits are the only race with real surnames, though some elves have the equivalent of that: Arwen Undomiel, Elrond Peredhil (sp.?). For dwarves, their names are in Khuzdul, which no man or elf knows, so the names given them are not their real names: Thorin Oakenshield. The 'son of' thing is used commonly, just as an additional, I suppose. Correct me if I'm wrong here, people, I'm not entirely sure. Some Rohirrim had last names: Eomer Eadig for example, but I know of no others. Same with the Gondorians, Orcs, etc...I'm shooting in the dark on this.
