Their story states that the family's assistance to the Christians exposed them to persecution. They were seized and delivered to the judge Muscianus or Marcianus, who, unable to persuade them to abjure their faith, condemned them to various tortures. Despite the torture, the saints refused to abjure. Maris and his two sons were thus beheaded on the Via Cornelia, and their bodies were burnt. Martha meanwhile was killed at a place called in Nimpha or Nymphae Catabassi (later called Santa Ninfa), thirteen miles from Rome. Tradition states that Martha was cast into a well.
Their relics later suffered various vicissitudes: some were transferred to the churches of Sant'Adriano al Foro and Santa Prassede, in Rome, and part of these relics were sent to Eginhard, biographer of Charlemagne, who lodged them in the monastery of Seligenstadt.
Their feast day (as indicated in the Roman Martyrology) is on 19 January. They were included in the Roman Catholic calendar of saints from the ninth century to 1969, when they were excluded because nothing is really known of these saints except their names.
