Hi PGC,
Well the best I can do is refer you to SIMBAD which at this page here lists all the objects with a catalogue designation within 120 arc-seconds of NGC 7012:

But I don't think the one you've arrowed is found in any catalogue so there is no info on it I can see.
The cluster, AGCS 921 from a perusal of SIMBAD does not appear to have been studied in any great detail (or indeed any detail) which probably explains why the individual members or supposed members have not been "tagged" in any definitive way.
Can't really help beyond that ...
Best,
Les D
