  We revisit the association of unidentified Galactic plane EGRET sources with
tracers of recent massive star formation and death. Up-to-date catalogs of OB
associations, SNRs, young pulsars, HII regions and young open clusters were
used in finding counterparts for a recent list of EGRET sources. It has been
argued for some time that EGRET source positions are correlated with SNRs and
OB associations as a class; we extend such analyses by finding additional
counterparts and assessing the probability of individual source
identifications. Among the several scenarios relating EGRET sources to massive
stars, we focus on young neutron stars as the origin of the gamma-ray emission.
The characteristics of the candidate identifications are compared to the known
gamma-ray pulsar sample and to detailed Galactic population syntheses using our
outer gap pulsar model of gamma-ray emission. Both the spatial distribution and
luminosity function of the candidates are in good agreement with the model
predictions; we infer that young pulsars can account for the bulk of the excess
low latitude EGRET sources. We show that with this identification, the
gamma-ray point sources provide an important new window into the history of
recent massive star death in the solar neighborhood.
