Have you tried to find the parents of Jessie Carey? If so, look for their death via SSDI. Then look for the obituary of both the mother and father. This might give you the remarried name for Jessie Carey and their grand daughter, whom you are looking for. If you can't find an obituary try and get the death record for the mother and father, the informant might be Jessie XXXXXXX. Good Luck
