Signor Uzielli has shown that one Tommaso da Vinci, a descendant of
Domenico (one of Leonardo's brothers), was a few years ago a peasant
at Bottinacio near Montespertoli, and had then in his possession the
family papers, which now form part of the archives of the Accademia
dei Lincei at Rome. It was proved also that Tommaso had given his
eldest son "the glorious name of Leonardo."
