Testing Novel SNPs to define the most recent parts of my branch

Normally SNPs are very old, but some are indeed possible to use for the last few generations. This is what I did to find out the latest details of my branch.

I am I1, did once test Z73+ and L1302+, but it’s a long time since those were my terminal SNPs. I am one of the admins of the i1-Z73 subclade projects (I1-L1301/I1-L1302) where we have found many new branches and several new levels of terminal SNPs.

After a BigY/Yfull test of my 6th cousin a few months ago (YF03087) I was defined as I1-BY2828 in the Yfull experimental tree (I am YF01888). We have the mutation BY2828 in common.

But Yfull also showed three remaining Novel SNPs of best or acceptable quality, personal SNPs that had occured on my line in the last few hundred years. Some time after the Most Recent Common Ancestor for me and my 6th cousin, Christoffer Norstedt b. 1672. I was curious to find out when.

I named the Novels JN01, JN02 and JN03 and wished them at Yseq.com.

JN01 wasn’t possible to test but JN02 and JN03 were made available for order at Yseq.

I swabbed my dad’s 1st cousin, sent the sample to Yseq, and now the result has come. The cousin is JN03+, but JN02-. I.e. JN03 occured before our common ancestor and JN02 after.

So now I know a little more about how my former Novel SNPs JN02 and JN03 are placed on my paternal line (some of the older SNPs are omitted, years of the older SNPs based on Yfull’s estimates):
