According to the family tree of the Abe clan, ABE no Seimei was born in Abeno, Settsu Province (present day Abeno Ward, Osaka City), as a son of ABE no Masuki, a low-ranking aristocrat who had the rank of Daizenshiki (there is also a lore that places Abe, Sakurai City, Nara Prefecture as his birth place).
安倍晴明は、阿倍氏の伝える系図によると、大膳職の官にある下級貴族安倍益材（あべのますき）の子として摂津国阿倍野（現・大阪市阿倍野区）に生まれた（奈良県桜井市安倍を生誕の地とする伝承もある）。
