The musicians who played for local dances would almost certainly have been the same ones who played in Church on Sundays. So to find out more about the instruments played, so you need also to investigate "West Gallery Music"

Paraphrasing what I have read and found out for myself over the past few years:

For about 150 years from roughly 1700 to 1850 music in the Parish Churches in England was provided by mixed groups of singers and instrumentalists. The name West Gallery arose because the singers and musicians were accommodated in galleries erected for the purpose at the west end of the church. The instruments were often provided and usually maintained out of parish funds. The parishes generally could not afford sets of hymn books so the parish would buy one or two copies of the hymnals and provide the musicians with manuscript books (which they usually had to rule themselves). The musicians would copy their parts into their manuscript books. They then used the back of the book to copy out dance tunes. Many surviving manuscript books are of this form.

This link provides an introduction to West Gallery Music

The link mentions fiddle, bass viol, cello, serpent, bassoon, clarinet oboe and flute. Trombone is also hinted at. Other brass would have been highly unlikely during the West Gallery period as valved brass was not invented until the end of the 18th century so brass instruments of that period were limited in what they could play.
