Paternity of Herman op den Graeff

No comment in two and a half years? Here's the Familypedia page for study:

Robin:
Do you think it's time to remove/replace the parental tie as there is no sourcing to show that Hermann Isaac is
the son of Johann Wilhelm, count of Jülich & Cleves and Anna van Aldekerk ?

I think it might be time as it is confusing as there are sites that say John WIlliam died without any kids and if you trying to do research on family and come across this saying this Herman guy is his kid then you may not know what to do..

Johann Wilhelm had no children. He had a nerve disease and became catatonic. A lot of doctors, healer and exorcists are not able to heal him.
I think an aristocratic family was good for Hermann Isaacs career, Someone create it later.

In addition to adding a specific curator note to Hermann, I've also added one to the purported father Duke Johann Wilhelm of Jülich-Cleves-Berg to hopefully minimize this from re-occurring.

No apparent refutation of the information I first introduced here in 2011. Here's a slightly modified version of what I recently wrote in a message:

'The "illegitimate son of duke" story has been roundly dismissed by several people. The most detailed that I have seen is at https://freepages.rootsweb.com/~uptegrove/genealogy/opden.htm (linked from the WARGS page noted elsewhere)

I may take the liberty of quoting it in full in case Ancestry.com decides to ditch Rootsweb pages:

'THE KLEVE CONNECTION

'There has been some noise of late about a supposed connection of the family with the de la Marck family, the hereditary Dukes of Kleve (Cleves). This story has it that Herman op den Graeff (1585-1642) was actually the natural son of John William de La Marck, the last Duke of Kleve and an unknown woman of presumably dubious rank. Unable to use his true family name, Herman took (or was given) the surname "op den Graeff," meaning, this author claims, "Of the count", which the author sees as a conscious clue to Herman's true origin.

'The great advantage of this Theory is that it provides an awesome array of ancestors of noble and royal rank for almost unlimited bragging rights.

'But there are some real problems with it:

'For example, this Theory leans heavily upon the similarity of sound between "Graff" (count) and "graeff" (graves, embankments or earthworks - note plural forms).

'Also, there is something of a mistranslation of that simple little preposition, "Op." This theory has it meaning "of", as if it were synonymous with "von," "van" or "de", so that the name would be Herman of the Count, but the usage of "op" in this instance probably means "above" or "over", with the connotation of "away from" mixed in.

' "Den", of course is the definite article showing the correct grammatical agreement with the noun, the dative plural.

'Thus probably the best translation of the name would be something like "up away from the embankments or earthworks."

'Another point against this Kleve connection: It is quite certain that a protestant activist named Abraham op den Graeff fled from the commune at Zwammerdam in 1561 to avoid capture by the Spanish, showing that this family name was in use well before the supposed father of Herman was born (1562).

'There are a number of other problems with this Kleve theory, but I think these two should be enough to discredit it.'

The WARGS site shows Herman and his wife thus:
Herman op den Graeff
* Aldekerk 26 Nov. 1585
+ Krefeld 27 Dec. 1642
m. Krefeld 16 Aug. 1605
3209 Grietjen Pletjes
* ... [Kempen?] 26 Nov. 1588
+ Krefeld 7 Jan. 1643

It shows no parents for him, but the note 3208 mentions the Abraham who was documented well before Herman's birth (clearly not having a surname that means "of the Count") and appears elsewhere in Geni.com...

I recommend that our curators examine the other Hermans in case a father Abraham seems to be "agreed".
