I agree, but I defer to Peter Roberts, The Bahamas category "admin", for bigger thinking ideas like this.
My age limited brain cells are down deep in the forest at the moment seeing how the new (to me) WikiTree+ facility works and might help. For some ideas, the query capability in WikiTree+ is limited (update also being unsupported to someone like me - at the moment), but that maybe can be "fixed" with appropriate cost-benefit arguments to the WikiTree+ admins which is being worked on.
In general, we can query/find certain things, but updating requires manual effort and often coordination with profile managers.
One example is that it is not doable - yet - to use a query to find Bahamas descendants that were not either born or died in the Bahamas. They should be categorized, as you suggest, as well.
And Peter wants to up the "integration" of WT and DNA matching especially utilizing GEDmatch. I think a very key effort from personal experience.
I'll look to see if/how surnames you listed show up in The Bahamas category query results. It's easier said that done, but essentially any profile that is Bahamian related should have the {{Bahamas}} category Tag as the fist line in the free textual portion of the profile - right at the top above == Biography ==.
