Ok, I went to the TolkienSociety web site and asked them what they knew about the death of Tolkien's oldest son. I got a response today. Here it is.
Quote:
Thank you for asking. There has been no announcement or obituary yet, and
the news-source of the announcement has not yet told us where he heard it.
Fr. John has we understand been very unwell for some time, but the news report is at present unsubstantiated.
That is the best answer that I can come up with about Tolkien's son John's death.
