Is the trail from William the Conqueror to Charlemagne really Uncertain? [closed]

Question

RF for Normandie-32 to Carolingian-77 says "Karolus Magnus is the 9th great grandfather of William I the Conqueror (Uncertain)" - caused by the "Uncertain" for Vermandois-351/Vermandois-1.

I've read through Vermandois-351 - the profile for the "Uncertain" daughter - a couple of times, and I can't figure out why the relationship with her parents is marked as Uncertain.

I've read through the father's profile too - it pretty clearly says everyone agrees that Adele is his daughter: https://www.wikitree.com/wiki/Vermandois-1#Two_Confirmed_Children

I was recently told that "The Henry Project" is the best source... But it shows Robert as her father too: http://sbaldw.home.mindspring.com/hproject/prov/adele001.htm

What am I missing?

Thanks!

Comments

The Uncertain flag goes back to when she was all confused and mixed up with Geoffrey's 2nd wife, whose parents are unknown.

Thanks RJ, I did have a look but couldn't quite work out where it originated from.

There is a bit of doubt in another part of that descent. See http://sbaldw.home.mindspring.com/hproject/prov/herib001.htm and https://groups.google.com/d/msg/soc.genealogy.medieval/8jTBE9CU3Aw/gkR3PcvJ_g8J 

The latter thread also discusses the link mentioned here.

Answer 1

Thanks Liz, I've just gone in and changed parents to confident, as you correctly point out there seem to be adequate sources that confirm the relationship.

The only slight uncertainty in the descent of William the Conqueror from Charlemagne, is whether Heribert II of Vermandois was the son of Heribert I, but Stewart Baldwin in The Henry Project makes it probable, and I think we leave it as confident.
