THX Ulf .
So Sigihart or Sighard the father
Mother ?

Not mentioned.

Supposedly this a direct ancestor for me, according to Geni pathways. However, when I got to this one, he has conflicting parents connected and I have no idea what the correct connections are.

Reading the prior posts about his parentage, it seems others have been uncertain as well. I always prefer that no parents be connected rather than only speculative parents because connecting unproven parents gives false lineage pathways here on Geni. When there is documentation to prove which set of parents is correct, they can always be connected.

In any case, this is a deadend for me since I don't know which path is correct from here back.
