My great grandmother died sometime after 1948. However, her surviving grandchildren do not know exactly when. The NYC site sends you to the Vital Check site for ordering death certificates and they require an exact date of death. If not, you're out of luck. Does anyone have any suggestions for helping me find her date of death? She lived in Queens, NY. She couldn't have died later than 1950-51 or my father and aunt would've remembered her.
