Hello Everyone,

I was wondering if someone with more experience would like to give me their opinion on a question I've been trying to resolve. The question is this: how do I determine what my TMRCA is, in light of my recent BiGY results. Or do I need to, considering the information I already have.

Judging from the results I've gotten, it appears that I have split up yFull's branch of

I-L234.

L-234 Y7200 * Y3648 * Y3655 * + 11 SNPs formed 2700 ybp, TMRCA 1150 ybp.

https://yfull.com/tree/I-Y3649/

Here are their current defining SNPs for L234

13038

Of those fourteen defining SNPs I am positive or presumed positive for nine of them. While being negative for L234, Y7200, Y3654, Y3650, & Y3648.

13039

So apparently FTDNA has split me off from L234 and given most of it's defining SNPs to my branch of I-Y7623. It has also put L234 just below F3527 and left it with only four total SNPs. Placing the last of those fourteen (Y7200) just below it's new placement.

So my question is this; how would I recalculate my TMRCA in light of the above changes, using yFulls formula of (# of SNPs x 144.41 + 60)? Or does yFull's L234 estimate of 1150 ybp still apply to me in spite of the divvying up of all those SNPs?

Anyway, thank you to anyone who would like to weigh in. I appreciate it.

Regards - jmcb

P.S. I have already ordered my Bam file and will be sending it off as soon as I can.
