However, because ABE no Sukune Seimei, instead of ABE no Ason Seimei, appears often in a group of ancient documents, and based on the practice at that time of strictly placing "Ason" above "Sukune," there is a view that considers him as a descendant of NANIWA no Imiki (later sukune) of the NANIWA no Kishi clan instead of a family that bears the ABE no Ason family name that originates from ABE no Miushi.
また、一部の古文書では安倍朝臣晴明ではなく安倍宿禰晴明と記載されるものが散見されるため、「朝臣」を「宿禰」の上位に厳格に位置づける当時の慣習から考えて、安倍御主人からの安倍朝臣姓の家系ではなく、難波吉士族の難波忌寸（のち宿禰）の末裔ではないかとする説もある。
