Wait, Peggy D. Buck was a South Carolina legislator, a Republican, who worked on education and social policies. If the network is named after her, perhaps it's a conservative policy group. If Susanna Ferring is a real person, maybe she's part of the same network or an associate. Alternatively, maybe the user is conflating two different entities. I need to proceed carefully. Let me start the essay by introducing both names, their possible connections, and the network's role in their work. If I'm unsure about details, I'll present possibilities and note that some information may be limited.
