I have taken the Family Finder test at FTDNA, I have 46 matches to others right now. Now it is up to me or them to contact each other and share our ged file or online tree, to see what surname we might have in common and then try to find what branch and person we might connect to with them. FTDNA does allow me to upload a ged file to my account that my matches can see, and I can also add surnames in my tree to a comment that my matches can see. The problem is that not everyone does either of these things.
Again for me, I have talked too, shared ged files with and confirmed 1/46 of my matches to a verified person on both of our trees.
I have one match (my closest one at 3rd cousin) that we have talked, shared ged files and still cannot find the connecting person. And we both have very extensive trees. It is frustrating be cause we know we should be able to find the connection because supposedly we are fairly close matches, but we can't.
Just because I have done the test does not mean that I might match a person who has my John Little in their tree. This might be your missing piece of info.
I think you need to seperate your thinking about the autosomal test from that of the y-dna and mt-dna and how connections are made with them.
I take the test and get my matches then I have to contact them and do more research to confirm how we are connected. As I said these matches are 2 living persons that are distant cousins who have a common ancestor.
So how I think it should work on wikitree is: if I confirm a match over at FTDNA and talk her into putting her tree here at wikitree. I then indicate on my profile that I took the test. Then there is a box to add confirmed Family finder cousin by inputing her profile ID number, Then hit connect. Then your program adds a automatic Autosomal DNA confirmation to all of the direct people between me and her.
Now if someone clicks on Daniel Gee they will see that he has that autosomal DNA confirmation on his profile and they will be able to click on that DNA confirmation ( takes you to the DNA page) and see how Daniel connects to me and my matching person Mrs Lawson. It would show up as an upside down V, Me on the bottom on one side and Mrs Lawson on the bottom of the other and our connecting person Richard Gee at the top, with the direct lineages of us up to Richard. Daniel Gee would be in the list on Mrs Lawson's side.
This is real, accurate, verified, helpful information to someone, that has been verified by the 2 people who matched and it is probably the most accurate info because there is the DNA and records proof of the connection. DNA gave us the clue, but records showed how we matched.
I hope my thoughts on this are clear
