Hey Retro,
I have Quilts from the Civil War and Civil War Women both by Barbara Brackman. I like both books.
Also, I just recently finished a little CW Repro wallhanging by Carol Hopkins Designs (Nancy's Glory). No books, but great patterns for wallhangings, perfect for gifts.
Here's the link to her website:
