I think Lancaster County, PA, may have scored a first: its own Civil War website.
Here's a little tidbit for the County's site: The Amish of Lancaster petitioned the federal government for exemption from military service during the ACW. It appears from this information that such exemption was not granted and the farmers had to avoid the draft for the going buyout rate of $300.
(Drop a line if I have garbled my Amish ACW history.)
