  Observations of the Milky Way (MW), M31, and their vicinity, known as the
Local Group (LG), can provide clues about the sources of reionization. We
present a suite of radiative transfer simulations based on initial conditions
provided by the Constrained Local UniversE Simulations (CLUES) project that are
designed to recreate the Local Universe, including a realistic MW-M31 pair and
a nearby Virgo. Our box size (91 Mpc) is large enough to incorporate the
relevant sources of ionizing photons for the LG. We employ a range of source
models, mimicking the potential effects of radiative feedback for dark matter
haloes between $10^{8}-10^{9}$ M$_{\odot}$. Although the LG mostly reionizes in
an inside-out fashion, the final 40 per cent of its ionization shows some
outside influence. For the LG satellites, we find no evidence that their
redshift of reionization is related to the present-day mass of the satellite or
the distance from the central galaxy. We find that less than 20 per cent of
present-day satellites for MW and M31 have undergone any star formation prior
to the end of global reionization. Approximately five per cent of these
satellites could be classified as fossils, meaning the majority of star
formation occurred at these early times. The more massive satellites have more
cumulative star formation prior to the end of global reionization, but the
scatter is significant, especially at the low-mass end. Present-day mass and
distance from the central galaxy are poor predictors for the presence of
ancient stellar populations in satellite galaxies.
