Estimating Relationships Based on Autosomal DNA

The amount of inherited autosomal DNA can vary greatly from cousin to cousin. I have a match who is 4th cousin, once-removed to me and two other people. Same relationship to all three of us. But she...

Dutch Ancestry

Mine does seem to show up as W. European. With the various admixture tools at GEDmatch, it seems to show up as German.

Triangulation Results

It's possible. But again, those two men who have different Y-haplogroups cannot possibly be direct male-line descendants of the same male ancestor. Can't happen.

Triangulation Results

I-M253 is very common in Sweden, while N-M232 is common in Finland and the Baltics.

Triangulation Results

Perhaps I am missing something, but if they are both direct male-line descendants of D they should share the same haplogroup - presumably I-M253 or N-M232.

Triangulation Results

I don't think you can"prove" your theory with autosomal DNA results, largely due to the imprecision of the autosomal relationship estimates. For example, Blaine Bettinger's crowd-sourcing project...

Too Long for So Far Back?

I would say it's unlikely, but definitely possible. I have one French-Canadian match of 71.3 cM, with the longest segment at 28.4 cM. Our most recent common ancestors seem to be eight generations...

Beats me, but definitely a glitch. Try deleting your kit and uploading again. Tokenization usually takes less than 30 minutes.

I personally have examples of both extremes: a 1/2 cousin who shares over 800 cM with me, and a 3rd cousin who doesn't even show as a match here at FTDNA.

The 1/2 cousin is also a 3rd cousin via...

Family Finder and Y-DNA Matching Problems

I am consistently having problems with both Family Finder and Y-DNA matching.

With FF, the "New Since" function is not working; the calendar icon seems to have a dead link.

A high frequency of "endogamy" often (but not always) produces an unusually high percentage of shared DNA, larger shared segments, and an inaccurately close estimate of "cousinship". I see this...

So GEDmatch made an exception to their new numbering rule for the Felix ancient genome kits? (I suppose the ancients can't sue over privacy issues.)
