I created this graphic to show how the 16 Groups in the Vance/Vans/Wentz DNA Project are related to each other.
Based on Y-DNA testing to date, all men on the planet are believed to be related to each other back about 300,000 years ago (which is before modern Homo Sapiens first appeared!).
Fast-forward to about 27,000 years ago in the Paleolithic era, and major haplogroups I, G, and R split from each other. From Haplogroup I descend 3 of the DNA Groups, Haplogroup G has 1 of the DNA Groups, and the other 12 DNA Groups are various flavors of Haplogroup R1b (M269).
Through to about 1800 BC (BCE), other branches split off and created new descendant lines. By 1800 BC (BCE) all 16 Groups had appeared.
Then anywhere around 1400 to 1800 AD (CE), depending on the Group, a common ancestor in each Group started having descendants who eventually led to all the men in the Vance/Vans/Wentz DNA Groups so far.
Each Group is marked on the Present Day line just alternating blue/orange to set them apart, and the size of each Group is based on how many men are in the Group so far. The Groups are sorted by haplogroups on the graphic and so are not in numerical order.
You can read more about each Group on the Results page here (select "About" first, then "Results").
Group 7 Post
Based on Michael Wentz (Cathy Wentz)'s comments below from Oct 29th on our earlier post, I have a new picture of how Group 7 likely shakes out.
The common ancestor of all of these descendants is a Wentz born in Eastern Europe or Russia likely around 1600AD - possibly the old Pomerania, which is one of the locations that the Wentz's are traditionally supposed to have originated.
There are two known immigrants of this Wentz family - one is Peter Georg Wentz, born in Russia in 1843 and emigrated to North Dakota. Our Douglas member, Nate Douglas, believes he is descended from this Wentz immigrant and the DNA supports that his Wentz ancestors are only connected to the others back around 1600AD in their original homeland.
The other members of Group 7 appear to descend from Adolph Wentz as Cathy describes it. One major line is an offshoot of Johann Michael Wentz b. 1732, the other appears to be descended from Michael Wentz b. 1736.
We do have a number of Group 7 members who have only tested to 37 markers - kits 808844, B10125, 296810, 95656 in particular, and I have no stake in selling DNA tests but we might be able to tell more if they were to upgrade to 67 or 111 markers. If this is enough for you for now though it's certainly more than other groups have been able to figure out!

Adding to Nate Douglas's post below, here's how we currently think the members of Group 7 are related based on the DNA results. The tested people are the yellow boxes and the blue boxes represent common ancestors of theirs where mutations would have occurred. The numbers in black above each box are the STR mutations that occurred on those lines. Known ancestors or groups (like the Randolph Co, IN Wentzes) are also marked where known.
The blue boxes also have time estimates listed in green on them - these are calculated statistically from the mutations that occurred and are just general pointers (they're not always precise). Although for instance the estimate for George Vance/Wentz in this case seems spot-on!
This picture is generated from a tool based on the most likely mutation patterns but we can adjust it as we know more about the genealogies etc. For instance Nate, if you're descended from "Gary" Wentz and we knew he was related to one of these lines we could slot you in there. RIght now your STR mutations don't show a common pattern with anyone else in the group so it looks like your Wentz line probably split off from these others around 1600AD (give or take 100 or so years).
With the help of a genealogist, we're 99.9% sure Gerhardt "Gary" Wentz was my grandfather. This has been an amazing journey and thank you to all the people I've met and who have helped me along the way! :)
