This is a hypothetical situation. How could it have happened?
A man told me in 2020 that his great aunt babysat Benjamin Franklin, who was born in 1706.
Again, this is hypothetical.
I will use a rounded upper bound of 40 years for the extreme age gap between siblings in a family,
90 years for a man to be a father, and about 110 years for the upper age for a man. (Yes, people
live longer than this.)
Birth year . . . 1690 . . . of the older sibling (eventual great aunt)
Birth year . . . 1730 . . . of the brother of the sister above (eventual grandfather)
. . . . . . . . . . . . . +90
. . . . . . . . . . . . ------
Birth year . . . .1820 . . . of the son of the brother (eventual father)
. . . . . . . . . . . . . + 90
. . . . . . . . . . . . ------
Birth year . . . .1910 . . . of the son of the son of the brother (current man)
. . . . . . . . . . . . + 110 . . . of the lifespan of the current man so far
