Holy Martyrs Alexander, Dionysios, Ingeniani, Pakeros, Parthenios and Saturninus

Aside from a reference in the fourth century Martyrologium Hieronymianum, we know nothing about Saints Alexander, Dionysios, Ingeniani, Pakeros, Parthenios and Saturninus except their names and that they were martyred in Thessaloniki. Some manuscripts have slight differences in their number and in the spelling of their names. They are commemorated together on April 1st.
