Really we have to assume Henry using that website to discover his mother and the fact Emma was in the book coinsidental. Maybe he was already trying to discover his real parents before Mary Margret gave him the book. Once he had the book and realised Emma was the savior he knew that he needed to find her and bring her back to save his "family and friends" in Storybrook. However after he discovered the website which we can assume from the plot on the show is a very very very good website for tracking down biological mothers (closed adoption or not) he also discovered that his mothers name was Emma. For a 10 year old to assume 1 + 1 = mother/savior its not hard to believe. He also really really believed it to be true and with the heart of the truest believer he KNEW his real mom was Snow and Charmings daughter. Plus as Utter Solitude mentioned, the curse had to insure Emma was in town to break it, or at least that was part of Rumples plan hence why he arranged for Regina to adopt baby Henry.
