She was presumably named after Gideon's mother, Barbara Pangborn.
- Clockwork Princess (alluded to)
- Nothing but Shadows (mentioned only)
- The Last Hours (set to appear)
- An error in a "found" family tree states that Barbara died in 1917, 20 years before the death of Will Herondale, which she and her sister, Eugenia, were present for.
- Barbara's presence in the upcoming trilogy The Last Hours is currently uncertain.
