== "Proposed Parent Family" == 

 This whole column needs to be removed.  It's simply not needed.  This chart is, by definition, for top-level language familiesthose language families that are not demonstrably related to any other.  In the currently constituted "Proposed Parent Family" are rejected groupings (Khoisan, Altaic, Caucasian), groupings that are still widely accepted (Niger-Congo), and groupings that have been recently proposed and have not received very much scholarly support beyond the original proposal (Austronesian-Ongan, Dene-Yeneseian).  In other words, either we list the "proposed family" as part of the list (based on consensus) or we drop it.  Listing fringe or rejected groupings in that column is simply doing a disservice to our readers.  There are so few of these anyway that the column is mostly empty.  Get rid of the highly speculative or rejected and there is almost nothing left.  It's a confusing and somewhat misleading column for our readers.
