We present a Chandra X-ray survey of the disrupted recycled pulsars (DRPs), isolated radio pulsars with P > 20 ms and B sub(s) < 3 x 10 super(10) G. These observations were motivated as a search for the immediate descendants of the approx =10 central compact objects (CCOs) in supernova remnants (SNRs), 3 of which have similar timing and magnetic properties as the DRPs, but are bright, thermal X-ray sources consistent with minimal neutron star (NS) cooling curves. Since none of the DPRs were detected in this survey, there is no evidence that they are "orphaned" CCOs, NSs whose SNRs has dissipated. Upper limits on their thermal X-ray luminosities are in the range of log L sub(x)erg s super(-1) = 31.8-32.8, which implies cooling ages > 10 super(4)-10 super(5) yr, roughly 10 times the ages of the approx =10 known CCOs in a similar volume of the Galaxy. The order of a hundred CCO descendants that could be detected by this method are thus either intrinsically radio quiet or occupy a different region of (P, B sub(s)) parameter space from the DRPs. This motivates a new X-ray search for orphaned CCOs among radio pulsars with larger B-fields, which could verify the theory that their fields are buried by the fall-back of supernova ejecta, but quickly regrow to join the normal pulsar population.
