It seems likely to me that Z5856 is indigenous to Spain, but was at some point absorbed by Levantine populations. How they ended up speaking Yiddish is anyone’s guess. Perhaps certain Sephardic groups joined Ashkenazi communities in Central Europe in medieval times. But I doubt Z5856 remained in Central Europe continuously.
Do we have a likely date of origin for Z5856? I believe Z1903 is 4000 years old?
