Florinus may have been the son of an Anglo-Saxon man and Jewish woman, who converted to Christianity and had settled at Matsch (Mazia) in the Vinschgau Valley on their way back from a pilgrimage to Rome.

[3] Florinus received his education from a priest at Unterengadin, where he was also ordained.

[3] After his death, numerous miracles were said to have taken place at his tomb in the parish church of Remüs.

After his death, the popularity of his cult increased, and his relics were distributed to various places, including the Florinskirche at Koblenz (in 950 AD) and also Regensburg.

[2] Vaduz Cathedral and the parish church at Matsch (Mazia) are also dedicated to him.
