Additional Information-What to incude

<p>I am applying for the University of Miami (Florida) and the University of Michigan via the common app. In the additional information section, what should i include? If i were to put anything in there, my main topics would be:
a) the fact that i moved from Michigan to Florida during the summer i was transitioning from a freshman to sophomore in high school
b) that my eldest brother attended the University of Michigan in 2006, and my second eldest brother attended the University of Miami in 2010 (there was no section throughout that application where i could list this information. It just said "grandparent alumni", not any kind of alumni).
Should i even bother including this additional information? and if so, what format do i write it in? essay? short response? bullet points?</p>
