Am I on the right thinking here.

Where there is a person who is/was the child of a casual or undocumented liaison the only proof may well be DNA.

In crime thriller parlance, means, motive and opportunity.

In searching for an unknown Great Great Grandfather, DNA points to a trio of Brothers, one of whom lived in the next village, that is as good as it gets, at least for now.

Hi Biggles,
Yes I reckon we are looking at something like that and we aren't even as close as you are, yet...... 
i am still working on all these scraps and i have come across cross marriages and brothers and sisters fron seperate families marrying but they are not part f the issue just in one of the families beign looked into . 

I will keep plodding along. 

Cheers Essnell.

Hello Everyone,
Essnell back again:....   yes

i have been working on as many of the scraps as i can.  now i have an interesting thing that i have noticed last evening. 

As i have said i had an invite to the DNA of the person looking for his grandparents  or more specifically his father's parents.  That got screwed up but i was able to get into some parts   yesterday through my cache back near when the invite was sent.  ,  I was able to see some of the results. 

Now i am looking at matches to the person who wants to know.  What i am seeing is that Ancestry has labeled people as on parent 1 side or parent 2 side.  I thought i had that sorted as parent 1 male and parent 2 female but it is not as clear as that. 

i really cant tell which side is which.  I am seeing the same people on both sides and the relationships provided are   way off the mark.
Everyone seems to eventually lead back to the same locality and the same root family. 

It is looking to me like just one big family with a division within that because of this undocumented parent.

Could he be part of that family and not someone from outside  that?   

Does anyone know how Ancestry would deal with such a scenario. 
here is an example .....

Person wanting to know has a half brother...same mother
Ancestry comes up with this:   
      1st Cousin or half Uncle,  14% shared DNA  976cM   37 Segs.    That does not make sense to me  at all. and there are others just as odd.   The half brother was adopted out. 

Anyone any ideas here.   

Thanks Essnell.

Endogomy screws up how DNA results are reported.

Can you advise each of the lines that Ancestry reports for the person especially the Unweighted DNA if it reports it?

Working through the Shared Matches may yield clues as might Pro Tools.
