Grandparents not great grandparents. Much closer.
They were ELVIS’S grandparents, therefore HER GREAT grandparents.
I don’t think that’s what the article said.
WRONG....
....again
LOL!
It was her great grand parents, Elvis’ maternal grandparents, but it doesn’t matter how far back the marriage was; Lisa Marie did have the gene which she inherited from them. The offspring from that marriage all died young from the same heart disease: Elvis’s mother, her brother, and Elvis. It doesn’t mean she didn’t also have blood clots from the vax in addition to the heart failure, and it could have exacerbated it, in fact I wouldn’t be surprised if it did.
