Aren't we missing some generations here?

The tree looks like this at this point:

Eylimi* (Elina) Hjalmthersson ?-688
her father

→

Völsung (b. 340?)
his father

→

Rerir (b. 290?)
his father

→

Sigi ODINSSON (b. 240?)
his father

→

Friege FREA 219-240
his mother

Meaning it only took 5 genereations to come from the 200s to the 600s. I find that hard to believe.

The years in brackets are my guesses. So we're missing around 300 years. Not that I know of any solutions, but can we find at least some of the missing generations?
