Do siblings count as legacy?

Hi everyone! Do siblings count as legacy or is it just parents/grandparents? No one in my family has gone to college except for my brother, so I was wondering it would increase my chances of getting into the college my brother is attending? (Can’t name the college for privacy reasons but it’s in the top 15).

Most colleges have a question on their college-specific application about whether you have any siblings at the school currently or who are alumni. So yes, colleges seems to value that.

The definition of legacy varies from college to college. It is often detailed on the school website.
