Chromosome Map

For those segments of DNA identified as HENDERSON or McEWAN (or possibly HENDERSON or WIGHT)
Click to enlarge

The chromosome map above shows the more likely segments of DNA that MAY BE Henderson related.
The reality is that they could have been inherited from the other of the pair of common ancestors shown!

The key lists the most recent common ancestor (MRCA) between the people whose initials are shown.
Where there is "anc." after the key name, the segment is part of a triangulated group (TG) of matches where we know there is a shared common ancestor, but have no idea, yet, where/when/who that shared ancestor is.

See also Lorna's HENDERSON page, particularly for the branches of the family represented by FamilyFinder tests, and those not yet included.

Segment Traceability

How about the pretty picture below showing the detectable DNA segments shared between some of the known HENDERSON descendant kits?
With thanks to the GEDmatch Shared Segment Traceability tool - and all those who have tested.
NB as this comes from GEDmatch.com it can only include those who have uploaded their atDNA file(s) to there.
At some stage it will be extended to include some of the closer matches as well as the known relatives, but I thought it was interesting to see the predicted relationship ranges, and how well they actually fit reality for WHEN there are matching segments that have survived down the generations.
Also to see the randomness of atDNA inheritance in action as to which generations actually do still have a detectable match with those down from a different ancestor.
The segments shown in the Key, and circle picture, are not of course the only segments inherited from Archibald or Margaret, just those where the assorted cousins have a match, and can thus be easily attributed to their appropriate shared ancestral couple.
