I’ve hit brick wall in my search for my great grandfather. It turns out he had a very common Italian name, so on at least 2 occasions, I’ve written to Italian Comuni and received documents for a different person of the same name and birth year. I’m pursuing Jure Sanguinis, and I had one avenue closed to me due to the “minor issue”. Finding my great grandfather would be my best chance now, I believe.
Here are my facts:
Luigi Negri - later anglicized to Louis in the US
DOB December 5, 1879
Arrived in US (according to 1920 census) 1906
Settled in Canaan, CT
Married April 1912 in Canaan, CT
wife’s name Marguerite Zazzera - later Margaret
Worked as a laborer for New England Lime Company in / around Canaan, CT
DOD March 5, 1929
So far, I’ve struck out with:
Viguzzolo - this Luigi returned home to marry a local girl
Spinetta Marengo - same situation here
One of the Ellis Island arrives had his last place of residence as Sampierdarena, Genoa
But when I reached out to the comune of Genoa, they could not locate anyone of that name being born there.
Any suggestions on where to try next would be very much appreciated.
