No, at least none known.
In fact, there is no proven link back to any Roman. There are,
at best, clues to a path that just might possibly be correct
to a Consul ( or rather, several of the same name) Tonantius Ferrouleous,
a person in Gaul at about the same time as Valentinian. However, there
are serious gaps in the proof chain. Other than this .... nothing
worth a comment other than "utter silly speculation".

When I looked at the speculative line from Valentinian III, again I wondered gullibility of some.
Yes, there was a marriage between a Vandal king and a Roman princess.
But their daughter, if such existed, cannot be proven to have married to Denmark; that's very implausible, incredible, hypothesis anyway.
and, then, simply, any lineages in Denmark are historically not attested between 500 and 900. There's nothing, no near-contemporary evidence, to establish any longer descents. It was literally Dark Ages.
Such lineal pedigree of Danish kings is simply a later concoction. Mostly out of thin air, with good imagination and creative talent for fiction.
So, there's dissected the advertised 'descent' from Imperator Valentinianus, third of that name.
We know that although he was betrothed to Licinia Eudoxia (his only
known wife) while they were both children, they did not marry until
437.
Then Valentinian was assassinated on 16 Mar 455 (in Rome, by Optila
the Hun as revenge).
We know that he had a daughter Placidia who was betrothed in 453 to
Flavius Gaudentius the son of the General Flavius Aetius (b c 396,
assassinated in 454).
I don't know what the source is that he also had another daughter
named Eudoxia who married Huneric, King of the African Vandals. It's
possible this is just a legend. Maybe someone has a source.
Other than those daughters, did he have any other children? And what
sources give either of those daughters children of their own?
If you can't find any CREDIBLE sources for any of that, then the whole
thing collapses.
