Recent history, readily applicable in terms of relation to author, Mr Frank Knight, had father Frank Knight. Both resided in Maryland later in life, both resided in Alabama early in life.
Working in the steel mills may have been an undertaking in common when they were in their early adulthood.
Knight Jr married his local and perhaps school sweetheart, in the area around the University. Knight Sr, married his mother, and later married again.
In the records obtained on the Knight line, at least for right now, 2025, going back several generations in the United States are not placed on these webpages. History beyond that might benefit from more evidence before public placement.
