I saw your post on Ancestry community and believe your family is in my lineage. Maria Michela deFabio married my grand uncle Amadeo Boccaccio. Her father was Arc Angelo deFabio and mother was Carolina Carducci.
Maria had a brother Matteo (Mathew) deFabio b 19 Oct. 1866 in Ripabottoni. He immigrated in 1898 (Ellis Island) and in 1900 Census was living (as a boarder) in Town of Murray, Orleans County, New York.
In 1910 census he was married to Anna and indicated he had been married for four years. They must have married around 1906. I have (as of 1910) their children Carolina b. abt 1907, Desolina b. abt 1909 and Lucia b. abt 1910.
Is this your family line? If so, I have more information on the deFabio genealogy. Would love to her from you.
