Thanks, Herbert, but even after seeking enlightenment in the 
documentation for the fontspec packagae I'm in the dark.

If I read the code you provide, I understand it to mean that I've 
selected a single new font for which I provide the command \Dunhill. 
When the command is called as in \Dunhill Dunhill, the word ill 
appears in the Dunhill font.

But the code fails to run. Run as you sent it results in this 
error:

  ! LaTeX3 Error: The key 'fontspec-opentype/    Scale' is unknown and 
  ! is being (LaTeX3)        ignored.

If I comment all the font feasures in sqquare brackets to run this:

  \documentclass[letterpaper,12pt]{letter}
  \usepackage{libertinus}
  \newfontface\Dunhill{latinmodernromandunhill}[]
  \begin{document}
    \begin{letter}
      \large \bfseries\Dunhill Dunhill
    \end{letter}
  \end{document}

I get the error: ! LaTeX3 Error: The key 'fontspec-opentype/ ' is 
unknown and is being ignored. 

Thanks for your patience.
