Hi Greg.
I'm quite familiar with that site. I began searching this site years ago and was directed to that one when Michael Madaus was still living and I was trying to find a flag maker who could make a 31st/49th flag for my father. My gg grandfather was Col. Jeptha Edwards of the 49th. I couldn't afford the prices and ended up becoming a flag maker myself and used information from the Flags of the Confederacy site to make a best guess version. My dad loved it and I've been making flags ever since. Thanks for all that you guys past and present do to preserve our history.
