Notes
If Merle was in Columbus, Ohio without Erlys in August 1887, and courted Erlys in Cleveland in early summer, that must have been 1888, so Dally wasn't born until around 01 Jan 1889, making her 14yo in 1903.
Pynchon's chronology for the 1893 Expo is overcrowded.
He's confused about Tesla's 1899 vision (03 July) and Colorado Springs experiments (later that year), and he seems to locate Webb's 04 July bombing in 1899 though Veikko's card is from August 1900, so it has to be 04 July 1901 or later.
The Stupendica leaves NYC in 1903, but when the passengers arrive it seems to be/become 1905 instead.
