In 2014 I met Diane Wiley Harman-Hoog
retired founder
She told me how DNA could help adoptees
Look through the family trees of 2nd, 3rd, and 4th cousin DNA matches for a common ancestral couple or two.
Build private, unsearchable family trees down from each common couple to find someone in the right place at the right time.
Sometimes you get lucky right away
What relationship is 1,614 cM?
1,614 cM and 62 segments... this chart is in your handout from DNA adoption - http://dnaadoption.com/index.php?page=dna-prediction-chart-pdf-2
Half Sibling or Uncle/Aunt/Niece/Nephew (Nibling)?
- Ages of the two people, what's possible?
- How Many Segments > 100 cM?
(half siblings will have 1-3+, niblings usually 0, rarely 1)
- Number of Segments from DNAadoption chart
- Can the X chromosome help?
(Sisters with same dad = full X)
- Can the haplogroup help?
Same mother shares mtDNA as does any maternal sibling
Same Y DNA haplogroup for a brother or paternal uncle

If you have a second cousin match with a tree, try the mirror tree approach

or https://www.youtube.com/watch?v=XyR_aBl89mId/
If you can get a Gedcom of your cousins tree that is easiest.
Uncheck the box that lets the public see your tree
