Family lore says that birth registered with the rabbi in Presov, Hungary (Lemesany/Lemes, Saros, Slovakia). This was confirmed by actual birth record from the Rabbi’s book. Looking at that book, Arthur Alexander (b. 1936) made the following observation, “‘Name of godfather or witness’ is the name Graf Paloviesi(ni) The last two letters only appear when I applied some Photoshop adjustments to the original photo. The end of the name was covered in tape, but showed through when tweaked. As I had thought, it is converted from the Italian, Count Pallavicini. --The Pallavicini's were a prominent, very old Italian family that spread through the Austro-Hungarian Empire. A search finds two palaces in the Kosice area of Hungary-Slovakia, two within 65 kilometers of Opina-Ofalu. One of them is now a hotel in Hungary. Another search finds several Pallavicini's with origins in Kosice. This, then, is the family for which the Alexanders served as managers or stewards. The fact that the Count witnessed Isidore (Israel) birth record suggests that the Alexander father was held in some esteem by the Count.”
