Definition of "armigerous"

Mr. Udal suggests that an armigerous woman who marries an non-armigerous man may still display her own arms. But how? Her husband has no shield, so where are the wife's arms to go?

Although the rolls of arms upon which Denholm-Young relied so heavily do not after all show that the esquires became armigerous in about 1370, it is still significant that the arms of esquires which were not emblazoned on the Parliamentary, Carlisle or Dunstable Rolls should appear for the first time on a roll of arms in about 1370.
