A Dictionary of Music and Musicians/Guglielmi, Signora
Appearance
GUGLIELMI, Signora, sang in London in Lent, 1770, in Italian oratorios, under J. C. Bach, with Grassi and Guadagni. She remained for another season or two, singing (1772) in Piccini's 'Schiava' and the 'Virtuosa' of Guglielmi. She was, perhaps, the wife of the latter composer, who was in England at the time, having come to London in 1768.
