Am I on the right thinking here.

[Essnell]

Hi  Yes I think so.  Today I was wondering if I could get Ancestry to pick out parent clusters.

Yes up the top it will cluster buttns for   ALL. Parent 1 or parent 2

 So I did both parent sides.  All parent 1 were the top 2 clusters and the last no 5.  Great s-i-l's mother's family .

That left parent 2  which was the the clusters 3 and 4 as I had thought.

 On that the top one is  Mabel's relatives  and other should be Mabel's partner and thence Frank's farther's relatives and that aligns with everything I have so far worked out.   At least I am not yet crazy.

it's now down to piecing together these few individuals together into some sort of related chart. 

Found another lot od connected Myrray people as well today so that's all helping.

Essnell  still hunting.

Hi   again,   
Any thoughts on this:   
working on this 7x7 cluster.
I have a gt gt grandfather married to two different women.  so GGF R   and GGM 1 has a descendant  L
   then  GGGF R  and GGM 2  have a descendant Z 

Now the DNA has that    L is related to   Z as  as 1/2 2 C    the shared cM is 164 cM   should this be correct or would 2C1R be more accurate.

Good progress E.

The 164cM indicates that they share has a wide range of relationship probabilities.

Looking at it and doing some head maths with me looking at the Possible Probabilities the result being 1/2 2C’s looks more likely, than them being 1/2 2C1R’s to each other.

Depending upon their ages and generational distances, one could be 1/2 1C1R to the other.

So the 1/2 2C is what I suggest as being the first line of research, moving on if necessary.

Hope L & Z are identifiable from their user details.

I do have a 2C1R that shares 96cM with me, it took a long time to resolve as he has a very popular forename and a surname that is very often found in the North West of England.

Hi Biggles,  Thank you again. 

I do know L's tree really well.  Z is a bit of an issue as it appears to be a different line from the same male person.  bit of a problem.  The surname/last name of relatives usually ends up as a private person everywhere I find them.   uhg!!

Z is the younger of the two I would think, as otherwise they would be the same generation.  They both have the same surname. 

I am also dealing with inter marriages between ethnic backgrounds.  So the customs etc become important to consider,   

Okay I will sleep on this and look at it again tomorrow.

Pedigree Collapse does mean that there is likely to be a higher shared cM than expected in the actual relationship which means the MRCA may very well be generationally further away.

So do go back at least three generations further with each if you can.

Hi biggles50 and David Nicholls, 
I set up a post or some thing earlier for here  --- lost it into the ether....

Now I was asking about this custom clustering and whether it would be useful to help with this mystery.  I also was not sure how to go about it but  I have given it a try. 

so here is what I got; 
I chose the person in this 7x7 cluster who has the biggest apparent connection to the others.  I also added Tanmika to it.  Now in just a minute or two  the cluster arrived on screen.  There were 4 -  each larger that the other from 1-4

1 has 12 members,  2 has 15 members  3 has 25   and 4 has 52.     
What is interesting there is that each successive one has new names added over those in the preceding one.   So those can be noted and isolated at another time..  each cluster only contained names for, in this instance, Parent 2 -which is where the mystery lies. 

I was then able to see the individual Matches from each cluster and the matches to those all quite foreign.  So it has picked up all those from the various match lists that also relate to this original 7x7 and that I do not see in the basic match list for S-i-l. 

Hence something extra to investigate.   This is going much deeper than I would have expected.           
Still no clues to the Mystery Grandfather. However it depends on what they already have in their database.

Now an interesting thing might be to include someone that should be related but there is no apparent connection .. thinking of known half relatives connected by the mystery person. 





Let you know what transpires.

The clustering will hold for a month  so till end of November for me.

Custom Clusters does seem to have quirks the worst for me being despite selecting DNA matches who are related Paternally it includes both matches from both Paternal Grandparents where I only want Paternal Paternal.

This is an issue because like you I am searching for that elusive Paternal GG GF so only want the cluster to display applicable matches and not having this feature can mean possibles are omitted from the results.

Can I suggest that you take screenshots of the clusters.

[David Nicoll]

Hi, I would agree with Biggles50, custom clusters seem to do some slightly strange things, I think largely to do with the lower match limit.
It’s quite good at visually showing the relationships, but not as complete as following shared matches and then shared matches of shared matches.
However as I am discovering in smaller communities, you can get into the situation where although you are a match to all of them, as you dive deeper you can switch from a match on the paternal side to a match on the maternal side, while their match to each other may be through a third relation.
It’s a matter of patience and building those trees.

[Essnell]

Hi again Biggles and David,
Yes, the screen shots are next issue.    I also have thought of listing the the persons added to each successive cluster especially the No 4 one as it has so many extras.  there might just be a clue in there somewhere.

I have an issue building some of these trees from the 7x7 cluster. Three at least have Australian Native persons as close as grandparents. Tracing those is very difficult if not impossible. 
 I know which part of Australia they originate from, the Native Tribal Nation. I have some of the tribal names as well as their adopted English name.   There appears to have been a Missionary Church in their area and this appears to have been quite an influence on the local people. 
I feel like this is a solid brick wall of silence. 

I will keep hunting...  next that Church.
