Recently my Living DNA family matching showed a match at 1.57%(114cM) with a possible relative (rel A). The paper trail suggest she was a half second cousin and we shared a great grandparent (My grandfather's father was unknown and we we suspected it was this man). All the other information we have fitted this idea. This great grandfather also had another family abroad and the DNA of a relative (rel B) was available on Ancestry.co.uk. This relative uploaded it to Living DNA and eventually matches appeared. However the levels of matching were not as expected.
All three of us should have the same great grandparent and are all three generations below him
My match to this relative was only 0.36% (26cM).
Relative A's match to her was much higher at 3.37% (245cM).(In fact it was higher than my match to her.)
Now in theory if we are the same number of generations below him I would expect the matching values to be roughly similar but they are way out.
How accurate are these matching figures?
Could the anomaly be a result of comparing Living DNA results with Ancestry which may not use entirely the same markers.?
Alternatively should I be looking at one of his relatives as either way the three of us are related in some way?
