Is Aliénor d'Aquitaine your ancestor? [closed]

+31 votes

Aliénor d'Aquitaine is one of the most fascinating women in European history. According to her profile on Roglo, a data base pretty much centered around European Aristocracy, Aliénor has over 1.3 million descendants in the said data base, this number representing more than 15% of the total number of profiles. The actual number of descendants of Aliénor is of course far larger than that, but how large?

My conjecture is that Aliénor stands at the right place and time to be a potential ancestor of about anyone living today and having European ancestors - that means I guess, over 99,99% of WikiTreers. What arguments have I to support this conjecture?

#1. Aliénor married a king of France and a king of England. In less than five generations, she had descendants all over Europe., from Russia to Portugal, and Scandinavia to Italy.

#2. The theoretical number of ancestors living in the 12th century, barring pedigree collapse, for someone living today, is in the 100 million range (based on a mean of 27 generations), which is the range of European population at the time. Of course if you are able to track your ancestors that far away in time, you are bound to meet pedigree collapse, and the more so if you attach somehow your ancestry to European aristocracy, who was pretty much endogamic.

If this conjecture is challenging, it's also certainly practically undecidable. If you actually have found Aliénor in your ancestors, it does comfort your belief in the conjecture, but it does not prove it true. But OTOH if you have not found her so far, it does not prove the conjecture false either, because you have not, and nobody will ever have, a complete list of your ancestors living in the 12th century (remember, potentially millions of them), which would be necessary to show a counter-example, if any.

True, false or undecidable, this conjecture is worth exploring, why not through a dedicated project here in WikiTree?

- Figuring out the actual number of Aliénor's descendants currently in WikiTree, and why not flag them (sticker, whatever)

- Working towards expanding the existing branches, in particular those spinning off the main trunk of European aristocracy.

- Any other idea ...

[edited 2021-08-03] : alternative form of the question : Who can track her ancestors back to before 1200, and has NOT Aliénor among them?

[edited 2021-10-12] : I have kept this post open, just to wonder how amazingly off-topic answers keep coming : most of them, sorry to say, seem to have just read the question title, and don't address the most important point of the post under the title, i.e., the possible (UN)DECIDABILITY of the conjecture.

Since this very point did not seem to get interest from anyone, the post is now closed.

Look above at what cousin Ed Trowbridge said.  I have a Trowbridge line, (on my dad's side, Carol-- you are on my mom's side), so a lot of those descents are tied up with the Trowbridges.  The royal and noble lines intermarry quite a bit. Not always a good thing.
Hi Cousin Carolyn, I figured that I was on the maternal line. It (the line from Eleanor) our shared maternal line. Take care!

She is my 25 great grandmother with 332 lines between her and myself. 

I tried to download every book that I could find on Alienor through , but one can only borrow each book for twelve days. 

Since this post has came back to life after one year of dormance, and for those who read French, for what it's worth, my own possible descendancy from Aliénor can be checked on this page, 31 generations, of which 8 are lacking in WikiTree to bridge a two centuries gap between Philippa de Laval (ca.1288 - 1350) and Jean Jégou (ca.1470 - bef. 1534). Having no qualification whatsoever in medieval genealogy, I won't venture in assessing the confidence of the missing links copied from various secondary sources, let alone add them to WikiTree. But if someone has both qualification, will and bandwidth, please proceed!

Hi Bernard, I don't really have time to look at this in depth, but to start with there are some problems with the dates you have on that list.  For instance, line 25 Jeanne de Beaumont-Brienne is older than her father, and line 24 Philippe de Laval, is about 47 when she gives birth to her daughter Blanche de Rochefort, not impossible but unlikely.

Moreri's 'Le grand dictionnaire historique ...' p. 20 although not perhaps ideal as a source, does have line 20 Guyon de La Chapelle as descendant of Ailette de Molac, but doesn't mention a daughter Mabille, unless this is an alternative name for daughter Marie, or Jeanne?  However Moreri has Guyon's son and grandson as Seigneur de Molac, which would make it unlikely that Mabille would be Dame de Molac.  

I wouldn't want to necessarily guarantee any of the lines from 24 to 15, but that relationship from lines 20 to 19 would appear to be the one most at risk.

John, thanks for taking the time to look into that, allowing me to fix dates at least! Jeanne de Brienne birth date was probably a copy-paste mistake, I've changed it to value given by WikiTree (1230 > 1263). Same for Philippa de Laval, (1335 > 1325). 

As for the rest, I agree with your cautious conclusion smiley

Eleanor is my husband's 31st great grandmother.

According to data analysis in "The pear shaped tree", less than 17,000 profiles in WikiTree were born in the 1200s. I've started to count the descendants of Aliénor born in the 1200s, will be interesting to figure which proportion they represent.

She's my 24th great-grandmother on my mother's side, with 100 different paths to get there, including pathways to her on my father's side as well, lol.

Not a descendant, but a second cousin 27 times removed.  That is, if you believe all 30 connections between me and Eleanor.  I think she is just a little too recent to be a common ancestor of everyone of European descent.

Thanks Herbert, very cool link.

Yes, maybe Aliénor is just a couple of centuries too recent to be a common ancestor. But she will be at some point. If you want to help, marry your grandchildren to proven descendants. wink

25th great grandmother with 480 other shared connections ;) I had already traced lineage to her on both sides of my family but found one pathway false when checking out the various Edwards III connections. I think these posts are a lot of fun! Thanks for sharing!!!

Per Wikitree, Alienor and Henry II are my 23rd great-grandparents, through their son, John. My DNA was done through 23andMe, and I've made it available on GedMatch. If this is of any interest in researching Alienor and/or Henry, I will be happy to participate.

I'm descended from three of her children, but have no clue how to find out how many descents that would make.

I'm guessing there is a way to find out using the family tree software (I have Reunion), but I don't know how, and doing it manually would take forever.

Can anyone tell me how to do this on Reunion? How to see how many descents there are from a particular individual but only to another specific individual?

She's my 24th great grandmother - 28th GGM depending upon which of the 112 paths between us you follow. All on my American father's side which has been so interesting, as my mother was a British war bride! How I wish they were both still alive to share all the connections I've found.
