A Dictionary of Music and Musicians/Byfield, John junr.
BYFIELD, John, junr., organ-builder. Nothing is known of his biography except that he died in 1774. The works of the two Byfields pass current under one head; but Dr. Rimbault is able to quote eighteen instruments (from 1750 to 1771) as made by the younger Byfield. The last six of these were built conjointly with Green. [See Green, vol. i. p. 624.]
