Nonetheless, Jean Baptiste Loeillet wrote some lovely suites for the
Harpsichord or Spinet, published in Broude Bros. facsimile; but they are
not very indicative of what was going on in the Low countries because he
moved to London in 1705 at the age of 25, where he spent the second half
of his life.
I also have at least one little piece by someone named Mattias van den
Gheyn, born in Brabant 1721, most of his working life spent as town
Carriloneur in Louvain. Also not calling for a second keyboard.
