Well, I belive that if you are positive on ZS4452 that is preety much "end of the road". You would be sharing common ancestor with us who had lived 3000 years before present (around 1000 BC).
Under ZS4452 you have ZS10589 (you are negative on it), ZS9952 (Ruddenklau and Maksimovic haplogroup; you probably not this, on DYS388 we share value 18 and you have 15 which is more common for other clusters) and ZS4375 ( which only have Moray). I also noticed one more branch under ZS4452 with name BY38105 shared by people from Portugal, Norway and Iraq. I only look at STR values of man from Iraq because others don't have public results, and I don't believe that you are this one either. (but you can check it; Kor either think that I work for Yseq
Maybe best thing should be, if you get positive on ZS4452, to wait a little until some thing in our branch become more clear.
Meantime, we can talk about possible ethnic identity of people who were carriers of this SNP (ZS4452). It look like they have enormous rise in period around 1000 BC. I was thinking about Arameans or something like that but there spreading, variance etc mostly look like pattern of old Israelites or some population close to them
I would like to hear what some other people think
