This evening, I searched microfilm of birth records (Atti di Nascita) from Serradifalco and found my great-grandparents, Angelo Palmeri and Maria Giambrone.
Not only is this an interesting tidbit, but I needed to make sure that these records could be found in order to apply for dual citizenship. This at least proves that these records existed when the LDS church microfilmed the Serradifalco records.
Angelo Palmeri, born 27 Jan 1886 in Serradifalco, Sicily
Maria Giambrone, born 12 Apr 1890 in Serradifalco, Sicily
