Did you know that Verdoni was known to be a chess champion in the 19th century, but what was his first name?
To expand BKFM's comment, this article says:
Verdoni, dessen Vorname und Geburtsjahr unbekannt sind, soll italienischer Herkunft gewesen sein. Sein schachliches Wirken vollzog sich in Paris und später in London.
This translates loosely as " Verdoni, whose first name and date of birth are unknown, was of Italian stock. His chess career was in Paris and later London."
