My maternal grandfather (Agostino Mattia, b. 1891 in Valmontone) emigrated to the US at the age of 18 in 1910. According to both a citizenship document (not attached) and his 1920 passport application (attached), he was naturalized as a US citizen (including renunciation of Italian citizenship) in 1918 in Battle Creek, MI.
I don't know for certain, but he likely met (or was "introduced") to my grandmother, Maria Attiani (b. 1902 in Valmontone) during that 1920 trip back to Italy. His grandmother was also an Attiani, so the families may have had an "arrangement".
He apparently returned again and married her in Jan of 1922. At that time, he was not only a US citizen for 4 years, but a US Army veteran (WWI) and had been an employee of the Ford Motor Company (machinist) in Detroit since 1913.
Yet on the marriage act on Antenati it shows him as a "resident" of Valmontone (making NO reference to his US citizenship) and indicates his social class as "contadino" (peasant farmer), which may have been the caste he was born into, he had certainly risen far above that working a specialized job at an automobile assembly plant.
So, what gives..? Did he (and his family) simply give false information..? Did the recording secretary simply ignore his status to facilitate the marriage..? Could bribery be involved..? Wouldn't SOMEONE in town know the truth..?
It just doesn't make much sense to me that on the document he is treated still as an Italian citizen, when clearly he was not. Thoughts..?
