This, being a Civil War, was so broad in its scope that almost everyone living through that era in the United States was affected. Some more than others, but even those that didn't serve in either army were greatly touched by this conflict.
If one of your ancestors was born between 1806 and 1847 then it would be worth searching to see if they were involved in the Civil War.
