This message is for Creeds in Haplogroup I1,and for descendants of Bennett and Matthew Creed in particular who are distantly related to my Britton family abd belong to the AS7E Subgroup of I1.
On Wednesday Dr. Ken Nordtvedt posted information on three new SNP's which may prove to useful in sorting out relationships within Haplogroup I1. When I asked whether he would recommend testing for subgroup AS7E, he said yes.However, since the three upstream SNP's (Z58, Z63, Z131) are believed to be mutually exclusive, he ordered only two of them (Z63, Z131) for himself, assuming that if he was negative for both, then he would probably be positive for the third (Z58).There are no known SNP's downstream of Z63 or Z131 at present, so a postive test for either would mean no further testing was needed at this time, whereas those who are postive for Z58 might want to consider further testing on one or more of several downstream SNP's.
The cost of ordering SNP's from the advanced menu is $29 each.If you decide to order:
Go to "tests and upgrades on personal page. Then go to "advanced tests" --- NOT "advanced SNP test" -- "advanced tests" is the lower link.
The cost of ordering SNP's from the advanced menu is $29 each.
DO NOT ORDER A DEEP CLADE TEST--Ken says they are a waste of money for I1.
I am sending this information to other AS7E's and hope we can find several volunteers in several different families.

Copy of post by Ken Nordtvedt:
"These 12 new snps for I1xL22 come from 1000 Genomes project, and now are in the FTDNA catalog for ordering. 1000Genomes indicate all branches have 2 or more dna samples derived; thus reducing chances we will run into “private-like” snps --- thanks for that. These snps seem to really divide the I1xL22 population. There are three parallel entry snps --- Z131, Z63, and Z58: Z131 leads to 3 dna samples, as does Z63, while Z58 leads to 9 dna samples. The rest of the new snps are downstream of Z58 and divide those 9 dna samples into several separate haplogroups.
And also we are here talking about only 15 I1xL22 dna samples, so we must expect some I1xL22 to escape being Z131+ or Z63+ or Z58+ (hence remaining I1*), but I don’t expect that population to be huge.
If one turns out Z58+ then, further downstream snps will probably be needed for you. If one is Z63+ or Z131+ then presently you will be at the end of the line with regard to these new snps and have found your new haplogroup.
Here are some of the further downstream alternatives that I1xL22 can become according to 1000 Genomes tree:
Z58 –> Z138/139 (they show two dna samples so mutated.) Z58 –> Z59 (they show two dna samples ....) Z58 –> Z59 –> Z60/61 –> Z73 (they show two dna samples ....) Z58 –> Z59 –> Z60/61 –> Z62 (they show one dna sample ....) Z58 –> Z59 –> Z60/61 –> Z62 –> Z140/141 (they show 2 dna samples .....)
/ indicate phyloequiv snps in face of just these 15 dna samples (but not necessarily remaining so after we exhaustively test further).
We don’t yet know how present L338+ haplogroup fits into this? They indicated some time ago none of their 15 dna samples seemed to be L338+, but I don’t know how firm that is?
I ordered Z63 and Z131 for myself. But if I had ordered Z58 I would also have ordered the downstream Z60 or Z61. That further downstream SNP roughly divides the 9 Z58+ dna samples into two equal groups, so if I would turn out Z58+ I would with Z60 or Z61 knowledge speed up learning where downstream I belong.
We I1xL22 people have lots of mapping to do with this new set of SNPs.
