Ok so I have two suggestions. One is to contact a local mortuary there and see if they can track down where she was buried. You have the date of death so it may be easier than you think. Two is to contact a local library there and see if they have access to any archived newspapers from the time. Most of the time they will be on microfilm. Once again having the date of death will come in handy there. The obituary may mention where she is buried. I think the mortuary is the best bet though.
