If I am trying to match Cousin Dorie who is likely a ninth generation descendant of our MRCA (myself being a 7th generation), is lowering the cM to 3 > acceptable?
For example, on 23andme I do not match Dorie, but mystery Janet matches both myself, Dorie, and my Maternal Great Aunt Beulah.
On FTDNA Dorie and myself do not match on the FTDNA Match List, BUT when I use the GEDmatch one to one comparison tool, Dorie and myself DO match as;
Minimum threshold size to be included in total = 700 SNPs
Mismatch-bunching Limit = 350 SNPs
Noise Reduction Threshold = 0.85
Minimum segment cM to be included in total = 3.0 cM
Chr Start Location End Location Centimorgans (cM) SNPs
1. 144,270,181. 149,763,826. 3.2, 724.
4. 47,317,237. 55,674,315. 4.4, 837.
8. 58,616,467. 61,778,015. 3.7, 731.
Largest segment = 4.4 cM
Total of segments > 3 cM = 11.3 cM
Estimated number of generations to MRCA = 7.2
With GEDmatch my sister Melody matches Dorie 2 times on Chromosome 1, and twice on 4 for a total of 14.3 cM's.
And Great Aunt Beulah matches Dorie once on chromosome 6, 4.0 cM, 848 SNPs.
We do not have access to Janet's raw data.
Dorie and myself have a paper trail for our MRCA, Dorie's is a proven trail, and mine is most likely from certain letters and documents.
Even though less than 7 cM's, can this be considered a match of our Relationship?
