One notable manner in which he both exerted influence and aided the mission was his involvement in and support of convents within his sphere of influence in Nuestria (for example Faremoutiers) into which some of the princesses of Kent, such as Eorcongota and East Anglia such as Aethelburg and Saethryth, in most cases his relations, retired and were made abbess.
The modern village of Faremoutiers grew up around the abbey which was endowed with lands by Saint Fara.
The other works of Jonas are lives of the abbots Attala and Bertulf of Bobbio, of abbot Eustace of Luxeuil, an abbey founded by Columbanus that retained close personal ties with Bobbio, and of the abbess Burgundofara (or Fara) of Evoriac (modern Faremoutiers).
