Looking for possible Family of Fusako Shinzato

Hello im currently looking for any possible relatives of Fusako Shinzato her married name is Ferrari. sometime in the early 1960s or late 1950s she married a marine and was naturalized here in the US in 1966. We know nothing of her family since she passed away when my mother was only 7 years old. She was born in 1939...if you know of any possible leads or useful info please email me [email protected]. it is very hard finding anything about her. thanks again Rose
