My cousin, Mary Rothrock Firestone Minnix (1846-1924) is said to be buried at Green Lawn (or Greenlawn?) cemetery at Welsh, Jefferson Davis Parish, Louisiana. This cemetery doesn't appear in Find All Graves or on any listing of Jefferson Davis cemeteries I would find (just a Greenwood, in another city). Does anyone know if this is really a cemetery?

Thanks,
Dan Stevenson
