my problem with the series timeline
This series of TV movies is, what, 6 or 8 generations long (and counting)? Does it bother anyone but me that the historical period in which "Westerns" is set was simply two short for all of these stories to fit in.
The period begins roughly with the end of the Civil War (1865) and ends at the turn of the 20th Century (1900). So it would be 35 years, give or take, recognizing that a "western" piece could perhaps be set a decade or so earlier or later. The constraints, from the clues found in these films, include the center-fire cartridge revolver(not available pre- Civil War), and the absence of motor vehicles, telephones, and other such technology.
So, allowing 20 years for each generation, that's two, maybe three generations. To place all of these episodes in a historical context and to set a date to each is, basically, impossible.
