A few months ago a statistic came out that stated that every noble house of Europe was related to Charlemagne and so I set forth to flesh my family tree out to try and find this correlation. I, of course, hit a dead end with an individual named Wigerius I, Seigneur de Beaugency.
I have a strong belief, although it may be biased, that Wigerius I is Charles de Courcy's son. Here is my thought:
In Lodge's Peerage of Ireland (1789) and the genaologist Edward MacLysaght point to a son of Charles de Courcy, Wigerius. How do we connect Wigerius de Beaugency to Charles de Courcy though? Well, these same references also indicate that Wigerius I had a son, Baldric de Beaugency. This Baldric also had son named Wigerius (as it was common to name children after fathers/grandfathers).
I believe it stands that reason that Londric (aka Wigerius Landry, aka Landry, aka Wigerius II) is Baldric's brother. Londric/Landry could also fit somewhere else down the line if need be. There are date conflicts with some of Londric's line (like how Ancelin de Beaumont was born in 1060 and then he had his son, Ivo fitz Herice, at the young age of 70).
If I can make this association then it ties the Harris (de Heriez/Herice) line into the Charlemagne line. I understand that I may be reaching for this answer which is why I'm asking for a second opinion on this.
To iterate my assumption once more:
We have loose ties between a Wigerius, son of Charles de Courcy. There is an association between Baldric, Wigerius's son, and Beaugency. It stands to reason that a Lord of Beaugency would have to be born of a house to hold the title which indicates that Wigerius I has some noble ties. If Wigerius II is Baldric's brother then we can link Wigerius to Charlemagne.
Your comments are appreciated.
