1. By which organization - All across the Confederacy patriotic ladies formed associations with names like Ladies Gunboat Funds, Ladies Gunboat Associations and Ladies Defense Associations to raise funds for ironclads.
2. By what nickname were these ships often referred to? These three ironclads, the Charleston, the Fredericksburg and Georgia were called Ladies Gunboats or as one critic derisively called them petticoat gunboats.
I also read that, "the CSS Georgia was unique in that it was built entirely from funds collected in the state of Georgia. It was very much a co-operative effort; the womens organizations, businessmen, the state and city of Savannah governments raising the funds and a board of advisors from both the army and navy."
Edit - "Ladies Gunboat Associations" is also being accepted as an answer for the first part of the question. "Ladies' Gunboats" and "Ladies' Rams" are also being accepted for the second part.
