No, we don't use galena is pencils. Galena is the primary ore of the metal lead, and this mineral, PbS, is recovered for that purpose. We also often recover silver as a byproduct of lead processing. It is graphite that is used in pencils, and the mineral graphite is an allotrope of carbon.
No, Roman children did not have pencils. Pencils, as we know them today, were not invented until much later. In ancient Rome, children would use a stylus made of a thin metal or bone to write on wax tablets.
