There are two different accounts of Phanuel. One that he was member of the Tribe of Asher, and the other that he was of the Tribe of Levi and a High Priest.
In the 3rd century, Clement of Alexandra (c. 150-c. 215) and Origen Adamantius (c. 185-254) identified the prophetess Anna as the mother of St. Mary. Luke 2.36-8 says she was daughter of Phanuel, a member of the tribe of Asher.
According to St. Hippolytus of Rome (c. 170-c. 236), Anna was the youngest daughter of High Priest Phanuel and his wife Mary.
