I am not saying this is the same family, but it is a rather odd coincidence; a DoS FOIA search for Elizabeth Deutsch which coincidentally contains the word subversive.

Then to broaden things a bit, just an FOIA search on Deutsch and it seems to be a needed dig…. like a letter from Raul Castro regarding the fate of the family.
