I don't have an answer to this question, but I'll ask it anyway.
I have a Google alert set for the word "Trautvetter." I don't get too many results from Google on this search and most are for articles written by an author who focuses on the airline industry. What is interesting is that there were no results in Google for obituaries for a relative with that last name who died approximately a month ago. The death notice appeared in two online newspapers and on the website for the funeral home. None of my Google alerts mentioned any of these items.
Not that I expect Google to tell me when relatives die, but it would have been nice if the items had appeared in my "alerts." Why they didn't I don't know.
Thoughts are appreciated.
