Emma J.
Plot information: Section 5, Lot 206, Grave 6
Burial date: 12 Dec 1938
Of all the E. J.'s listed, only Emma is even close to the plot listed. Will do more research to see if there's a better fit somehow else.
After more research, the full headstone for Emma has been found. Will see about photographing it and comparing how close this marker is to it.
