Trivia: Due to an impending writer's strike, the script was completed in only 11 days by writer Alan B. McElroy. McElroy cracked the story, and managed to complete a final draft in this short period of time, reportedly turning it in only a few hours before the strike began.
Question: How were Rachel and Jamie able to make the connection that Michael was Jamie's uncle?
Answer: It's never explained who told Jamie of her murderous uncle, but Jamie is mocked and made fun of by her classmates for being related to the infamous Michael Myers. She could have been told by her adoptive family, classmates, neighbors, etc, but the movie never provides any definitive answers.
