McKenna Foundation Resource Room
The Park Service also maintains the McKenna Foundation Resource Room, which is a great way to find out if you are a descendent of 1 of the more than 3,000,000 men who fought in the Civil War, or 1 of the more than 160,000 men who fought at Gettysburg. Volunteers will help you chart out your family tree. Open seven days a week and free to the public from 10 a.m. to 4 p.m. daily.
