Confirmed it is the right people and family.... Now the question is what became of Edward as there are several Edward Greenberg's in 1940 US Census and one is a 'nephew'. And what became of Sarah.
I requested a picture of Joseph and Rosalind's tombstone at Mount Hebron.
I got a copy of Joseph and Sarah's marriage certificate and Rosalind's death certificate on FamilySearch.
Greatly appreciate your leads! More than you realize <3
