Dear List For those who tested positive for Z63, or Z58 and/or one of its downstream SNPs and are not members of the I1>Z58+ and I1>Z63+ Project at FTDNA, you may find the Project’s Surname SNP Tree a useful guide if you are trying to decide which downstream SNP to test next. This chart is updated regularly, but I thought I would share a link to the latest version because there have been some positive results for Z73 and Z382. I will leave this file in my Dropbox account for a short period of time in case anyone wishes to download a copy: Surname SNP Tree link (ver. 11 Mar 2012): http://db.tt/97FNiNm1 SNP Distribution Maps Links: Z58+ Map: http://g.co/maps/gd879 Z63+ Map: http://g.co/maps/ahnxj I1>Z58+ and I1>Z63+ Project website: http://bit.ly/I1Z58andI1Z63 Kind regards Julie Frame Falk
