In general, they usually dedicate their writings to a loved one. Like their wife/husband, kids, or people that have greatly influenced them throughout their life. Also maybe someone that has helped them a lot with the book they wrote. Then when they pick a person, they sometimes use inside jokes in the dedication, or for a wife, "for my one and only love, Olga". something along those lines, usually. They don't really just put a name of a person, but rather say what they think about that person or why they love them so much, why they inspired them, and so forth. That is mostly what I have noticed... I read the dedications in each book I read =).
