Sorry to reply to myself. Hearing from no one for almost a week, I decided to "check around" again and see if I couldn't find some way to restore Google Chrome ...
This posting gave me the idea to "downgrade" the application:
Looking in my system's /var/cache/apt/archives', I found all recent upgrades to google-chrome-stable. I decided to re-install the previous update version:
google-chrome-stable_49.0.2623.75-1_amd64.deb
I then attempted to apply the package using this:
# dpkg -i google-chrome-stable_49.0.2623.75-1_amd64.deb
