Sam,
It would be interesting to see if FindAGrave would accept Douglas as a "Famous" memorial. I don't know if you have submitted others for the "Famous" designation or not. If not, you might want to read the requirements for the bio. In its present form, the bio on the memorial would not pass muster and would likely be rejected on the grounds that it does not conform. The guidelines can be found here: http://www.findagrave.com/cgi-bin/fg.cgi?page=bios
Looking at a few "Famous" memorials might also be helpful to see how they conform to the guidelines.
