Carl And The Teurings

In 300, Carl visits the thorp that is the home of the Goth Winnithar of the Teurings above the Vistula, where he also meets his host's wife, Salvalindis, and their daughter, Jorith.

Using future technology, he repels a Vandal attack and takes the sixteen year old Jorith as a leman but she dies giving birth to their son, Dagobert. 

Carl, a time traveler, has started a line of descent in his own past. Poul Anderson's "The Sorrow of Odin the Goth" follows this family from 300 until 372. Carl, benefiting both from time travel and from futuristic longevity treatment, visits his descendants throughout that period.

However, since the time here is now 12.45 AM, I will resume this summary of the family's history some time tomorrow or the day after.
