Looking for the burial sites of Jefferson H. Jones and his wife Tryphena I. Jones both known to have died in Jackson Co., Oregon. March 28, 1916 and April 10, 1929. Their son Leslie may have also died there on August 31, 1935. Jefferson and Tryphena were raising an adopted daughter, Evelyn F. Rogers who was 8 years old in 1910. Would like to find descendants of Leslie or this Evelyn Rogers. If anyone can help me with the burial sites, I use would appreciate it. I live in Columbus, Indiana.
