  Particulate Dark Matter (DM), completely isolated from the Standard Model
particle sector, can be produced in the early universe from Primordial Black
Hole (PBH) evaporation. However, Big Bang Nucleosynthesis (BBN) observations
put an upper bound on the initial mass of PBH requiring the PBH to evaporate
completely before the advent of BBN. DM particles in the mass range
$\sim(1-10^9)$ GeV can not explain the observed relic abundance for an early
matter dominated universe due to this BBN constraint. However, this assumes the
presence of only one monochromatic PBH mass distribution in the early universe.
In this work, we explore the simple possibility of achieving the observed relic
with DM masses from the above mentioned range for an early matter dominated era
with two monochromatic evaporating PBH mass distributions and demonstrate that
the fermionic DM masses consistent with BBN change slightly.
