Conjecture
Chris Griffin's name predates the popularity of the Seth McFarlane animated comedy Family Guy. The son of Peter Griffin in Family Guy is named Chris Griffin. Sandi Griffin's younger brother might be given a different name if the show were created today, or at least some reference would be made to his sharing a name with a cartoon character -- particular one like the Family Guy Chris Griffin, who is portrayed as an overweight moron.
