I am the Archerd showing on Ken Nordtvedt's I1 L22+ Tree. Various tests taken some time ago at Ethnoancestry and FTDNA established that I am DF29+, CTS6364+, CTS10028+ and L22-. In April I received my Full Genomes results, which confirmed what I knew and seemed to add the following after CTS10028: FGC2488+, S6346+, Z9853/FGC7561+ and F4092+. My private SNPs start after that. Apparently there has been one other sighting of F4092+ (NA20512). Greg Magoon informed me that the other sighting is a R1b person from Tuscany. [F4092 = ChrY 8109742.] I had the Full Genomes results analyzed by YFull, which reported that my terminal SNP was CTS6364/Z2336 and that I was I1a1*. YFull said that CTS10028 and S6346 were "equivalent or upstream" of I1a1. I joined the L22 group at YFull to see if I could learn anything about the point where I might break away from L22+ people. All sixteen L22 group members were CTS10028+ (ChrY = 19217149). Ten were S6346+ (ChrY = 3662036). My "brick wall" has been confirmed but at least I have my private SNPs identified. I will keep hoping for a cousin.
