Regarding the death of Julius and Chaya Mussa

The following corespondence is from Gloria:

Jeffrey, It is wonderful having this family connection. I have been unable to gather details regarding Jules and Chaya Mussa's date of death or cause of death. Perhaps your mom, Shush, may have an answer. I recall my mom, Miriam, saying they died 6 weeks apart.
Does your mom have an email address and where does she live?
Have a good day. We are expecting a major snow storm in CT. Gloria
