It's a fake beard because she's going to the stoning later.
Gustavo: The short answer is no. They never released any nonmilitary lower class Romans. The Martin beggar is arguably one but a) St. Martin dates to the fourth century A.D., a bit after the first century Roman theme, and b) his rags are such that he could be from almost any time and any place within a couple thousand years - there's nothing "Roman" about him.
So we Romanophiles have to make do. First, we dragoon likely suspects: the Maries, Josephs and shepherds from the (first century!) Nativity sets 5588, 5719/3996, 5958, 4884, 9494, and 4885/4332 for children. Note that all the various wise men make excellent non-togaed nobles or foreign merchants/princes and so forth. 9373 is also essential - note that you can remove Noah's toga and he looks a right pleb. 3255/5276 less impressive.
In fact you can remove the togas from the regular togaed Roman figures and create more or less serviceable commoners from the denuded klickies - just ignore the gold trim!
That's the main sequence, some more ideas later
