Elvis has Irish, English, and Scottish ancestry. About his roots, he has stated:
I’m English, but my ancestry is Irish, and they used to say the same about the Irish as well [‘These are the people who are the source of all your problems’]. My [then-wife, musician Cait O’Riordan]’s Irish. Sooner or later, we’ll probably have to leave England – because I’m sure the people of England will try and send the Irish back.
Elvis’ paternal grandfather was Patrick Matthew McManus (the son of John McManus and Elizabeth Costello). Patrick’s parents were Irish.
Elvis’ paternal grandmother was Mabel Josephine Veronica Jackson (the daughter of William James Jackson and Mary Elizabeth Malcolm). The surname Malcolm likely indicates Scottish ancestry.
