How can you find Saint Damian who was a Roman soldier from Novara?
I have search and can find no Saint Damian of Novara who was a Roman soldier. I have found a Saint Damian of Africa who was a Roman soldier and martyr, however. Perhaps this Damian of Novara is a local saint not recognized by the Universal Church.
Try doing a search on any popular search engine for 'patron saint'. There are many sites where you can conduct that type of research on the Web.
