NN van Bierum - Father?

It surprise me that people are certain about dates on a profile when you don't even know the name ;-)

his grandfather
Rudolf von Werl, Graf im Mittleren Friesland
has a good link to information
http://fmg.ac/Projects/MedLands/SAXON%20NOBILITY.htm#HermannIWerle985
a lot is uncertain of not known
if you like to dig deeper, be my guest
Hendrik Niklaas, Henk Hummel has made the connection.

Jacobus, it's NN that needs researching not Rudolf.

As you say Rudolf is well known, his son Rotho, Bishop of Paderborn is more questionable, the only info i can find is the German wikipedia, they do list a source book which maybe Justin Durand has access to.

There is no suggestion that Rotho/Rudolf married or had any children.

I cannot find anything online about a "Rudolf Rudolfz van Fivelgo"

The profile NN van Bierum only has a reference to a website so doesn't count for much. His birth date is calculated/guessed (Bjorn) based on the births of the following generation, which are probably guesses in themselves :)

I have a bit of a vested interest in this profile as it is my only vertical path into the World Tree:
NN van Bierum is your 23rd great grandfather.

Just to clarify the article in German Wiki is not certain of Rotho's parentage.

English Wiki says he is of the von Werl family but doesn't even speculate as to how.

I don't know if he even gets a mention in wiki.NL

so, what is you suggestion
break te link? I don't care.

No suggestion yet, just questions :)

I was thinking about this last night

The profile of N.N. van Bierum is created only on the basis that Bishop Hardbert and his brothers must have had someone for a father, we don't actually know if his name would have been van Bierum.

The only hint of a link to the von Werl family is that Bishop Rotho was also known by the name Rudolf von Büren, but then it is not certain who Rotho even was.

So we have a real person that might have been in one family connected to an unknown person who was definitely in another family.

Hendrik Niklaas, Henk Hummel, I really would like to know what evidence exists for this link.

Failing that, George J. Homs,could you suggest any sources that might connect van Bierum to von Werl?

I have disconnected NN van Bierum from his "father", no new evidence has come to light and i think 3.5 years was sufficiently patient of me :)
I have also locked the profile's relationships so that he cannot be reconnected, hopefully no one gets too upset.

I have left Rotho, Bishop of Paderborn connected to his "parents" for the time being, although Medlands does not connect them, as he would otherwise become a floater.

Sorry Alex,
I completely forgot about this.
I hope I have not given you much trouble.

No trouble at all, i'm excited that someone is interested in these profiles but we need to be looking for evidence to support these theories.
