Hannah and Barbara
Hannah Williams and Barbara Josephs are business and legal advisors to, and functionally the official administrators of, the Quill Organization until Jason turns 18. (Although the details of his transition to 'ownership' of the Foundation are somewhat cloudy, owing to the existence of a "Foundation Board" and the legal separation from the Quill Foundation, Quill Industries, and especially the Menagerie).
The two women are both business partners and legally married in the state of North Carolina. While both reside and have their primary place of business in Halcyon City, Barbara most often operates from the Williams & Josephs, LLC, offices locally, while Hannah does the traveling, most frequently to Washington, DC, to lobby or represent the Quill organization interests.
