Forgot to mention, that on the St. Louis Post obits, for the year 1900, there is a Robert Durphy Sr.
Click on WEBREF on the top of the page and request the obit, I think it is only a dollar or something like that. I am unsure where you write for the death record at. It has been awhile since I requested one before 1910, when death records were required.
Please post what you find out, if you do this, This is interesting.
Was Louis Guerette a sister to Pelagie Guerette? Pat
