Scrap closeness: what is your most distant connection in the global tree?

Lots of fun can be had with the new connection finder. (In addition to its usefulness when exploring villages with a lot of intermarriage between families).

Just for fun, I have been looking around for my most distant connection. So far I have only been able to squeeze it up to 51 degrees.

That's if I use myself as the anchor in one end. If I make the connection to someone far out on a limb in the Swedish past from the person I'm 51 degrees from I should be able to push it up.

Hah! I tested you with the newest "French notable" I painfully managed to connect, and you're 60 degrees from him. (It is a very fragile connection, I'll admit. This person is 24 degrees from the nearest profile with several connections, and there is no other path that I could find unless it's through a few placeholders for living people).

Meet Jean Gabin: https://www.wikitree.com/index.php?title=Special:Connection&action=connect&person1Name=Ekeblad-7&person2Name=Moncorg%C3%A9-1&relation=0&ignoreIds=
I just say: Wow!!

I can't beat that! Well done Eva and Isabelle! laugh

Bravo Isabelle! I saw you were working on Jean Gabin, and the path you found to connect him is indeed a long and windy one. But I'm sure his distance to everyone will go down over time when new connections are found. 

My own distance to Eva is 33 degrees, going through my wife's family and the (in)famous Thorn branch. If I strike out my wife in the path, the shortest path is 43 degrees long, passing through my newly discovered cousin Suzanne Gardahaut. It figures that just adding a node can reduce a lot of distances.

The connection finder explores the graph using all the possible directions - parents, children, spouse(s), siblings - If every node has a mean value of three neighbours (a very conservative number), you can reach billions of nodes in about 20 steps (3^20 > 3 billion). If each node has five neighbours, your reach the billions in 14 steps. 

Those theoretical values are actually consistent with the current geometry of the graph. Distances over 50, and even over 40, are the exceptions, and should be reduced in the course of WikiTree growth. This is a very cool paradox, the more people we add, the closer we are from each other :-)

Yes, this game says a lot about where the global tree is thinly populated.

Since I viewed it as a game, I didn't consider it as cheating to use time as distance.

But now I wonder about my most distant WikiTereer colleague.
This made me curious, so I checked my connection with Bernard. We're 28 degrees - and I suspect this could be shortened by 10 degrees or so without much difficulty.

If I strike out my well connected sister-in-law and Bernard's wife, we are 32 steps apart. Which is surprisingly short as this path only goes through very ordinary French citizens (it goes through the ancestry of a very distant cousin of mine with Breton ancestors). https://www.wikitree.com/index.php?title=Special:Connection&action=connect&person1Name=Vatant-1&person2Name=Rassinot-1&relation=0&ignoreIds=25193000%2C23078618
So I check my connection to Maria Lundholm, which is 17 degrees, going through her husband, with whom I have a common ancestor seven or eight generations back.

Striking him out it's 28 degrees, going straight back on my side to Arvid Andersson (1669-1740) and then snaking down on the side of Arvid's sister through a chain of marriages.

https://www.wikitree.com/index.php?title=Special:Connection&action=connect&person1Name=Lundholm-24&person2Name=Ekeblad-7&relation=0&ignoreIds=13511828
I'm 38 degrees from Eva, 32 degrees from Maria, 34 from Isabelle, and 31 degrees from Bernard. I'm 58 degrees from Jean Gabin.

Most of my connections go through Queen Sonja of Norway, my 6th cousin twice removed. It makes sense, because royalty is well-researched and closely connected. The Queen and I both descend from common people in Lower Telemark.
42 degrees to Leif if I strike out the American paths.

@Eva : "But now I wonder about my most distant WikiTereer colleague."

Indeed this is maybe where my above speculative computations are the most relevant. I'm pretty sure you won't find many beyond 40 degrees among the "active" WikiTreers. (say, over a few thousands contributions).

I agree with Bernard. The reason why there's about 40 degrees between Eva and me must be that both Norway and Sweden are sparsely documented here on WikiTree. I'm pretty sure that the distance between us could be halved, going exclusively through commoners, given more contributions.
I took a quick look at the Swedes with project badges and the biggest distance I got was 38 degrees, with somebody who has added just one line, going far back.

Maybe one should make a hobby of adding a few sideways-connections in the late 19th century now and then and see what they meet up with.
This is fun! I take that connection to Eva of 28 jumps, and strike out person after person (nobles) and still we are 28 jumps apart (after striking out at least three persons already).

Has this been allowed?

 I seem to remember a discussion a while ago, about how the system would take hours every night to make these billions of connections just to connect all of us to every profile in the system? And this is why there was a 10 degree restriction in place.

Why the change?

Thanks to the marvellous work of Aleš Trtnik.
Announced 17 September.

17 Sept?

Oh dear. I am behind the times.

Thanks Eva!!
And thanks to Isabelle. I realised from her answer that I can 'strike out' my husband from the connection finder. I get so annoyed  when almost every connection is via his South African relatives.

Eva is 34 degrees from me, 26 via husband.

The strikeout feature is very nice to have.

laugh Samantha this one is unfair. Of course if you go back 2,000 years even in direct ancestry line it takes over 60 generations. This is the limit to my above comment, which was more about the distance between currently living people.

LoL! I have 78 degrees to Xiu-1

I'm only 70, thanks to the direct "aristo" line of my wife. wink

If I strike her, 78 like you, Eva.

Eva, thank you for starting this convo.  I learned a lot about using the connection finder by playing with it.  I'm 28 degrees from you, 25 from the Bernard Vatant profile mentioned previously.  Can you tell me how you found the furthest person?  A random stab in the dark probably isn't where you started . . .

I started by looking for early, but still connected profiles in Asia. My first attempt - through the category system - was a Chinese person living in Indonesia = 51 degrees. Of course it would have been smarter to go straight to China and use WikiTree+

I was surprised and a little embarrassed when Isabelle brought in Jean Gabin. I just didn't think of France. That path is also very impressive with so many lateral connections.
Thanks for the idea Eva.  I found Asinii-1 who is 64 degrees from me (using Asia).  IDK how to get WikiTree+ to givem e the oldest birthdates without some text to go along with it.  My first French connection is 30 degrees.

The WikiTree+ query to give the connected profiles with the earliest birthdates is: https://wikitree.sdms.si/default.htm?report=srch1&Query=1Cen+Connected&MaxProfiles=500&SortOrder=BiDa&PageSize=100

Thanks, Paul.  The first one on the list is:  That was very interesting with the Chinese Emperor, quite a few from Mecca, and about 1000 years of French. 

Xiu Liu is 70 Degrees from Cindy Cooper

Eva, another way to figure the graph connectivity is to start from a robust, heavily connected node, and count the number of profiles at distance 1, 2, 3 etc. 

I've started to do that with my great-great-grandfather Jean-Joseph Marie Vatant (1804-1875), who had 9 children of Marie-Anne Hamonou and 53 grandchildren (if I don't miss any). As he had also 10 siblings, and of course 2 parents, this makes 22 profiles at distance 1.

At 2 degrees only, I found (as of today) 114 profiles! I've started gathering them in a dedicated spreadsheet smiley.

At 3 degrees ... I'm still counting, but suspect the figure will be over 500, and at 4 degrees in the thousands (including me).

When I'm more advanced with those figures, I will post about them, as an illustration of the fact that there are way more people at short distance than we usually think.

Sounds like a substantial task you have given yourself :-)

YES! But that's because I want to stay alive for quite a few more years. In the same spirit I engaged a few months ago in a crazy online Go (the game) tournament which, given the number of participants (more than 2,000) and the settings allowing very long delays between each move, is likely to last about 60 years, if not more. That gives me yet another reason to stay alive. L'espoir fait vivre smiley

Eva, now that our 100 Circles project is up and running, please add our trademark tag "100_circles" to this thread, for further easy retrieval.
Did that ten seconds before you posted ;-)
