Just a thought, there are copies of the book, "The Caroline Light, Parker and Stafford Light Virginia Artillery" by Homer D. Musselman available on the "net". I got a copy from Amazon a couple of years ago. This book is part of the "Virginia Regimental Histories Series" and the first edition has a 1992 copywright by H.E. Howard, Inc. of Lynchburg, VA. The book contains a brief history and full roster of troops from each of these three Artillery units.
