On July 4 68, Marciana bore Patruinus a daughter and their only child Salonina Matidia.

He served as a praetor and through this position, Patruinus entered the Roman Senate and became a Senator. In 70/71, Patruinus possibly served as Governor of Upper Germany. Upon this death in 78 in Rome, Patruinus was a priest and served as a member of the Arval Brethren.

After Patruinus’ died Marciana and Matidia, went to live with Trajan and Trajan’s wife Pompeia Plotina. Patruinus was the late maternal grandfather to Matidia’s daughters from her three marriages who were: Roman Empress Vibia Sabina who was Emperor Hadrian‘s wife, noble woman Matidia Minor or Mindia Matidia and noble woman Rupilia Faustina.

The Italian village of Matigge (ancient Matidiae) is named after him and his second granddaughter Matidia Minor. The Roman Emperors Marcus Aurelius and his successor Commodus are among his descendants.
