Send a message to the person who requested a photo of the grave monument of Pietrina Sorrentino with the following comment:
We have been looking for a Pietrina Sorrentino from Queensland, who is the sister of my father-in-law, to inform her of his passing. It is sad news to think that she may have died also. This monument photo may assist in identifying if she is the person we are looking for. Your assistance would be greatly appreciated.
