How satisfied are you with your DNA test experience?

[davidft]

Just had an email from a cousin

who has an Ancestry tree and has (so he tells me) done his DNA etc...

Now our relationship is that his Great grandmother is My Great grandmother 's  sister.

AND yet Ancestry says we are NOT a match.....


what a waste of money ...

So now -- do I have to investigate what my Great Gran got up to!  or what his Gt. Gran got up to.. does this mean that my Gran was not the daughter of my .................and on and on and on... for ever.  Not playing this game anymore..

Going back to the old fashioned way pre DNA

end of (that's a term my grandchildren use.. and it fits... )))

Well there could be a whole host of reasons for this.

1. The two of you are not related despite what the paper records show as there was some extra marital event somewhere along the line that breaks any link that was there
2. The amount of DNA either of you have inherited from the GG Grandparents (6.25% X 2) you supposedly have in common is small, add to that what you inherit is at random and so the two of you could have inherited quite different parts of the genes and this is why Ancestry is not picking it up
3. What ever confidence levels Ancestry is using is above what the two of you have in common so although Ancestry says you are not related that only means at the levels they tested
4. Ancestry made a mistake - it happens

Thanks for that David, you are right and I am an impatient .. miserable .. old.. wotever.. ha ha

We are working it out and it does seem it may well be  a double relationship issue... naughty g.ggrandad..


So hope Ancestry forgives my moans... I should be shot.

Autosomal DNA can be lost very quickly.

Let’s call the 50% of DNA a person inherits from their father an Apple and the 50% of DNA they inherit from their mother a Banana.  They marry someone with 50% of DNA, which we will call a Cherry and 50% of DNA, which we will call a Date.  The first child inherits the Apple and the Cherry.  The second child inherits the Banana and the Date.

No match.

Xin, Have either of you uploaded to Gedmatch or anywhere else where you can confirm whether you do share any DNA at all?

According to ISOGG, ancestry picks up 98% of 3rd cousins, you could be in the unlucky 2%, though perhaps unlikely.

If you are sure that you are not related, then one of you has an incorrect tree, and no amount of basic paper research will correct it, unless you investigate it further.  If you are descended from one of great grandads 'illicit relationships' (for want of a better term), then some of your tree will be based on a lie.

No match.

I see your point, but the likelihood of that happening is practically zero.  Again, according to ISOGG, probability of no detectable DNA starts at 2nd cousin once removed stage (0.1%).

Margaret,

I agree.  I was merely illustrating what "could" occur.

Just had my DNA results  from Ancestry. Not a lot of surprises as to ethnicity:

Ethnicity Estimate
Ireland/Scotland/Wales
64%
Europe West
15%
Scandinavia
14%
Great Britain
5%
Wales & the West Midlands
Northern England & the Midlands
Low Confidence Regions
Europe South
<1%
Finland/Northwest Russia
<1%

And, what a surprise, it lists my great/grand nephew as my nearest relative- high confidence  Also a 3rd/4th cousin who helped me when I started all this and sadly died in NJ a while ago.

Not sure what to do now - do I go through the list and make contacts
