Beth David, (Old) Montefiore, Washington: All three cemeteries are predominately Jewish, and –apparently– each has a marked section for Kletskers. At Beth David, some Kletskers chose to be buried elsewhere, in a private section.
Note that any given reservation was not necessarily used. Spot checks against Findagrave were inconclusive.
