Richard,

Thank you for the answer.

You are correct, the message was not intended for the list.

You are also correct in that I should have created a new record and 
added references.  My own institution has undergone name changes and 
there are NARs for each name, each with references.  I knew that, yet 
somehow made this mistake.

But in the changed record, the references were removed and in the new 
record there are no references.  It seems clear that the two are the 
same, even the Isthmus article mentions Midland, Texas.

The two are linked by earlier-later see-also references. I've understood this to be so that the earlier name can still be used on records for material entered under that name; also, when corporate bodies change their names, they often change the nature of what they are, through merger, de-merger, and so on.
