Arnoldo Spadini (1895-1901) found in his private family archives an important document, known as “the Judge's Diary”, written around 1855, which contained interesting information about the ancestry and descendents of the judge, Giovanni Antonio Vanoni. He read it through and decided it was worth typing, and he made a few copies of it. One is in the possession of Arnoldo’s daughter, Carmen who occupies the old Vanoni home in Aurigeno, Switzerland. Another copy was sent to Erminia Vanoni Morelli. When she died, the document became the property of her eldest child, Elizabeth Morelli Perry, and when Elizabeth died, the book was lost during settlement of her estate. Although the text is in Italian, translation was not too difficult, and it was very helpful in the preparation of this descendent report for Tommaso Vanoni. In the meantime, a little book, "L'istoriato di mia vita," which reproduced in its exact style the judge’s handwritten text, was printed in 2010. Raffaello Ceschi, the Historian of Canton Ticino used this document to comment on the justice in this period. Sandro Bianconi, a linguist, commented on the style and the spelling and Denyse Bertoni shared part of her own research on the complex genealogy of the Vanoni family. 

So far, various researchers have found four Vanoni branches, designated as Borra, Princes, Mola, and Rossi. In 1800, another Vanoni branch designated as Ferrazzini was split from the Mola line. Tommaso Vanoni and his descendents are members of the Borra and Princes lines although they later mix with Mola and Ferrazzini too. It is believed that all five lines converge if we could go back one or two more generations.
