  We aim at establishing safe membership and evolutionary status of 11
chemically peculiar (CP) stars that are residing in the domain of the open
cluster NGC2516 and are frequently referred to as cluster members. We queried
the Gaia EDR3 catalogue in an area with a radius of 1deg and selected 37508
stars brighter than G=19mag. The cluster membership was determined in
parallax-proper motion-space and 719 probable and 764 possible members were
found. The obtained average astrometric and photometric parameters of the
cluster are in good agreement with the most recent literature data. The
evolutionary status of the target stars was determined with respect to Padova
isochrones. After minor adjustments including the metallicity, the reddening,
and the transformation scale variation, a perfect fit of the model to the
observations over the whole observed magnitude range was achieved. Only 5 of
the 11 considered CP stars could be classified as highly probable cluster
members. Among the Ap/Bp stars with previously detected magnetic fields HD65987
and HD65712 have a high membership probability and the magnetic star CPD-60
944B is a possible cluster member. Further we discuss the blue straggler nature
of HD66194 and the magnetic star HD65987. To our knowledge, HD65987 is
currently the only known blue straggler, with a field of the order of a few
hundred Gauss. The most striking result of our study is that the strongly
magnetic A0p star HD66318 with previously reported very low fractional age does
not belong to the NGC2516 cluster at a high level of confidence.
