Dear Patricia,
Hi, I just read your post and my family is also Citarella's. Unfortunately, I don't know that your father is related, but I wanted to ask if you checked the social security indexes. It will tell you the date of death and you can then go to the archives and check the obituaries for the local paper, or you can send for a death certificate. If you tell them you are the daughter, and need the cause of death information for medical reasons, they will leave it on. If you have any questions please contact me at JOYCDP@aol.com.
God Bless!
