Zelia Trebelli-Bettini (1836β1892) also known as Zelia Gilbert or by her stage name Trebelli, was a French opera singer.
Mme Trebelli's artistry was greatly admired by George Bernard Shaw, who wrote about her a number of times in his various reviews.
In particular, he admired her interpretations and her exemplary English diction, rare for a non-native English speaker.
Her daughter Antonia (originally Antoinette) Dolores Trebelli (c.
1864 β ) was a distinguished soprano, and as "Mademoiselle Dolores" was well received in Australia and New Zealand.
