This question showed how naive I was.  Sectionals don't have well-
defined boundaries.  Most have a well-defined SW corner of latitude and
longitude (on the South side) and extend to the North and East from that,
but several extend vertically to some horizontal (to the image, not a
line of latitude) line.  Then there's Jacksonville with its insets.

Regardless, the SW corner is a good place to start for this.  Here's my
list.  Corrections will be appreciated.
