Hello George,
Thank you for indicating in WikiTree that you have tested with 23andMe.
Please register at GEDmatch.com and follow their directions to upload your 23andMe results there. Then add your GEDMatch ID at
https://www.wikitree.com/wiki/Special:DNATests .
Also at that WikiTree page, under “Add New Test Information”, select that you have taken an "Other yDNA" test.
In the y-chromosome haplogroup field enter your paternal haplogroup as reported by 23andMe (it is found under 23andMe’s “Ancestry” tab). In the "Optional space for additional information" field enter that your paternal haplogroup was reported by 23andMe and include the approximate date you tested with 23andMe. Adding an Other yDNA test will allow WikiTree to automatically associate your Y chromosome (i.e. paternal) haplogroup with your direct paternal line.
Also, here is a short video which shows you how to let your 23andMe matches see your ancestral tree in WikiTree: https://www.youtube.com/watch?v=OerZbCUrn0U
However you need to also add your ancestry to WikiTree (and hopefully connect to your earlier ancestry already in WikiTree) to make the above information useful.
I welcome any questions. Most sincerely, Peter
Peter J. Roberts
