This might look like Jakob Pettersohn, but it's actually his father. When they're both over a thousand years, their age difference is basically a rounding error.

For those wondering about the surnames, they have a patronymic tradition so Jakob Pettersohn is Petter's child, Niall Jakobsohn is Jakob's, and so on.
