The curator Flemming Allan Funch is responsible for the area around Harald Bluetooth and are currently performing a major cleanup in that area, so we should let him make decisions on this.
The Private manager you refer to is however an halfway unclaimed account, so if you can post a link you the Geva Knudsson you mention it would be fine.
Well, the name Geva is news to me too. A lot of people have entered the name like that, but I haven't seen any kind of documentation for it. Anyway, since everybody seems to agree that he's identical to Gorm the Old, there's no major problem with it.
Gorm's parentage is rather uncertain, and there might very well have been several Gorms. But I'm so far assuming that Gorm the Old is identical to Gorm Engelske (Gorm, the English).
There are other things that a lot of people do in that area that I'm aware of no documentation for. Lots of people link either Gorm or his son Harald Bluetooth up with a "de Crepon" family in France. Which is surprising to Scandinavians who haven't heard of any such connection and it is probably wrong. The de Crepons do seem to come from a Danish viking king, but probably somebody named Harald a couple of generations earlier.
