  There have been increasing theoretical speculations and observational
indications that certain globular clusters (GCs) could contain a sizeable
population of stellar mass black holes (BHs). In this paper, we shortlist at
least 29 Galactic GCs that could be hosting a subsystem of BHs (BHS). In a
companion paper, we analysed results from a wide array of GC models (simulated
with the MOCCA code for cluster simulations) that retained few tens to several
hundreds of BHs at 12 Gyr and showed that the properties of the BHS in those
GCs correlate with the GC's observable properties. Building on those results,
we use available observational properties of 140 Galactic GCs to identify 29
GCs that could potentially be harbouring up to a few hundreds of BHs. Utilizing
observational properties and theoretical scaling relations, we estimate the
density, size and mass of the BHS in these GCs. We also calculate the total
number of BHs and the fraction of BHs contained in a binary system for our
shortlisted Galactic GCs. Additionally, we mention other Galactic GCs that
could also contain significant number of single BHs or BHs in binary systems.
