Dynastic Names

What dynastic name is being suggested here?

Note that Sven was using a matronymic (Estridsen) rather than his patronymic (his father was named Ulf), probably to emphasize his descent from Svend Tveskjæg (Svend Forkbeard).

Both cited Wikipedias seem to be saying that he used the "Estridsen" (Ástríðarson) himself; it was not something imposed by later historians.

In this case the name is hidden by the Display Name.

Here the dynastic name is "Jelling". Some curators put a dynastic name in the Birth Name field. Some don't. Strong feelings on both sides.

Elna Kirstine Plougmann has been particularly vocal. I think it's best to let her make her argument herself.

"Estridsen Ulfsen" - what the h. is that kind of combination?
OK, - his fathers name is Ulf, but he has in most text I have read about him been referred to as the son of his better known mother, i.,e Estridsen.

Aside:
I see I Curate Sveinn - by default of identifying him in a Curator Note as Shakespeare's 'Sweno' in Macbeth. I'm happy if Bjorn or Harald want to take over Curation to make sure the name conforms to whatever you decide at the end. Otherwise - just let me know how it should change.
