Percy saves him
In the Odyssey Polyphemus had no wife. In Percy Jackson (Sea of Monsters) he wanted to marry Grover (or Clarissa) but did not succeed.
All we know about Grover's parents is that his father was a satyr who went searching for Pan and never came back. It is possible that his father died on Polyphemus's island, since it is revealed in the second book that the nature magic of the golden fleece smelled like the great god Pan, and led many searchers astray.
Grover goes missing on his quest for Pan, Camp Half Blood's magical borders are dieing, and Thalia's tree is poisoned.
Chapter 15 is about tricking the cyclops Polyphemus and trying to escape with the Golden Fleece.
Odysseus tricked Polythemus by telling him that his name was "Nohbdy." When Polythemus shouted for help, he yelled "Help, NOHBDY has blinded me." When the other cyclopes heard that NOBODY had hurt him, they laughed and went back to their own business.
