Today on ebay I tried to buy a document. Unfortunately I was unsuccessful. Three people, Luigi Fiacchi, Francesco Pontecorvo (your grand grandfather, I believe) and Enrico Mariani, on 8th May 1908 wrote this long document (36 pages) to protest again rigged elections in Valmontone. It would have been very interesting to know the details about this facts. I asked the vendor to have a copy of the document, I don't know if he will agree... Here is the link to the ebay page:
Got it! Thanks to the vendor who sent me the full pages. There is the description of buying the votes with many many details and names. At least 4 of them are my relatives. No more news about Francesco Pontecorvo, however.
Eh eh eh... among other things, actually the document describes how 25 liras were left at Vittorio Giorgi's house to buy his vote. But the men who left the money was wrong, because those 25 liras were intended for another Vittorio, Vittorio Balzoni. So neither the first nor the second voted for the "buyer"...
Today I found an interesting document. In 1807, a group of 120 Women, chosen among the most wealthy and exemplary in the town, started a "Company for Charity", with the aim of helping poor and ill people. They called themselves "Sisters of Charity". Among them there was Marianna Monti, widow of Giuseppe Pontecorvo, and Cecilia Pontecorvo (her daughter??). Among the witnesses there was Mattia Pontecorvo, son of Marianna. The document gives also the info that the two women came from the Santo Stefano's parish, the same of my family. Klo, Marianna Monti was 6 generations before you.
