In the 1940 US Census: Dorothy, George had their first son Jerome - https://www.ancestry.com/sharing/24230673?h=e48734&utm_campaign=bandido-webparts&utm_source=post-share-modal&utm_medium=copy-url
They checked all George Cohen at Riverside and their sexton records - no match with Dora AKA Dorothy and Doris or wife’s name, sons and their spouses were on it and age range and year of death.
I am sending a request for both of their birth certificate to see if we can find George’s parents names and Dora’s legal name. It will take a long time as NY Vital records take FOREvER :-(
