I am trying to locate the gravesites for my great-great-grandparents, Herschel Vespasious Pitts (b. 1/24/1860, d. 9/30/1937) and Vitula Demaris Fyke/Fike? Pitts (b. 2/28/1866, d. 8/3/1951). I have their last known residence as Saint Helens, Columbia County, OR, but I'd very much like to know which cemetery/cemeteries they are buried in. If anyone can help, I'd greatly appreciate it!
