In 1929, author Frances Gillmor published "Thumbcap Weir" which was set on a West Isles Parish, New Brunswick island titled "Deadman's Island" which was connected at low tide to a "Thumbcap" which held a herring weir. The island appears to have been modeled off Jouett's Island and Hospital Island and situated impossibly north of Spectacle Islands but south of White Horse Island.https://archive.org/details/thumbcapweir0000gill/page/206/mode/2up "Gillmor, Frances.
