Some interesting anagrams of GidgetGirl are Digger Gilt (especially as there seems to be some suggestion of Silver Mining on the maps) and Rigged Gilt. I'm not sure if it matters that "guilt" is not spelt correctly.
Could be a reference to 'gilding' where a thin layer of precious metal (usually gold or silver) is applied over wood or plain metal to make it look flashier.
An anagram of Darla Taft is "Fatal Dart". Could this hold any significance?
Sawyer gets a dart stuck in his foot just before returning to the beach from Hydra Island.
