Pasquale Prosperi has been in Toluca (after having been in Putnam for a while) approx. between 1902 and after the 1910 Census (he was back in Italy by 1920 Census). He was born in Spoltore, Pescara, Abruzzo, Italy on Sept. 23rd, 1869 and died there in 1950.
Family stories say he had two children in Illinois. I can estimate they were born between 1903 and 1919. I'm quite positive about the fact that they did NOT carry the surname Prosperi, since he was married in Italy.
Looking for info about him and his descendants in the States.
