Technicallyyyy before the full switch she had little Ludwig, since the mana loss happened after his father died.
It doesn't have to be his own kin. It's just that in Ludwig's case, the dude took his mom's body. But in the flashback we saw from Olive reading the contents of the book to Ludwig, the black haired body may not have been biologically related to the white haired one. Whoever inserted mana into Ludwig's mom may also not have been a blood relative either.
so you're telling me, the author of the research about immortality is basically the ancestor of ludwig, and he leaped through bodies of his own kin just to extend his own lifeline. WTF SO YOU'RE TELLING ME LUDWIG'S MOTHER AIN'T THE MOTHER AND IT'S THAT LUCAS DUDE WHO'S BEEN TRYING TO POSSESS LUDWIG OMFG
