Furthermore, precise Arab ancestry of the Roman emperor Philip the Arab is not known, since all sources give only the Latin names of him and his family members. However, having originated from the general area in which the Ghassanids settled, many historians consider he may have been of that origin. His being mentioned either as a Christian himself or at least tolerant of Christians would fit with his originating from a people which was in the process of Christianization at the time of his rule.
