A Sackett wrinkle that never happened

Sacketts were always bumping into kinfolks in the Louis Lamour novels; that was a regular feature of the series. For example, the Cumberland Sacketts had occasional contact with the Clinch Mountain branch of the family. But one story that Louis never got around to was to bring the line of Jubal Sackett. He went west several generations before the rest of the family, and it would have been a nice twist if some of the Cumberland or Clinch Mountain groups had run into Jubal's offspring.
