FROIM KATZ from Piatra Neamt - Romania, arrived in the US in 1910 aged 21. He went to his brother Isadore in Grand St. New York. I notice that a Frank Katz, 450 Grand St, New York, was naturalized in 1912.
Additionally in the SSDI there is notice of a Frank Katz (birth dates co-incide) who died in 1974 in San Mateo, California.
If anyone has knowledge of Frank, his family, or extended family, please contact me.
