Step brothers. 3 of them.
His Father Vernon remarried in 1960 to a woman named Dee Stanley. Dee had 3 sons from her 1st marriage (aged 7,6, and 4).
Elvis was not happy about his Father re-marrying so soon after after the death of Gladys, Elvis’ mother. And he saw Dee as a gold digger on top of that. He hated her.
Dee and Vernon started carrying on an affair while she was still married to her first husband, an Army Sargeant, which also only infuriated Elvis.
Couldn’t he take his father’s allowance away?
