My full paternal uncle and I enough cM with an outsider to both be listed as half siblings to an unknown male. My uncle shares more cM with that unknown male than I do (a female).
Both my uncle and I are listed as half siblings to this person. I don't understand how two different generations of known lineage can be half siblings with with the same person.
Here are the numbers:
Uncle and "the male outsider" 26% shared DNA | 1,809 cM across 41 segments Unweighted shared DNA: 1,809 cM Longest segment: 125 cM 100% 1/2 sibling
Me and the "male outsider" Shared DNA: 1,655 cM across 28 segments Unweighted shared DNA: 1,655 cM Longest segment: 165 cM 100% 1/2 sibling.
My Uncle and I Shared DNA: 1,599 cM across 41 segments Unweighted shared DNA: 1,599 cM Longest segment: 125 cM 99% uncle
Can you start to unravel this?
