After 1000 years I'm pretty sure that every Irish, English, Scottish person has Viking veins as does most Poles, many Germans and Russians too Ditto for Jewish blood in most peoples

I've also seen it written that the Spanish,at one time,made their way to Ireland.If true that would help explain the “black Irish”.Also,it's not difficult to imagine that people from Continental Europe might have some Jewish blood but I doubt many Jews made their way to the tiny island of Ireland.But I suppose I could be wrong.

Well, the "Spanish" of today, if we look back 1000 years they called themselves Castiliano or more simply Romans or Christians or Moslems (yes, quite a few converted). If we look back 2000 years, then they called themselves different names including many with Berber or Phoenician blood

The Spanish did come to Ireland during the age of discovery, but the phoenicians probably came there as early as 1000 BC

The "Black irish" refers to their hair and eye color not the color of their skin

As for Jews, remember that they were kicked out of their homelands around 200 AD after they had slaughtered thousands of gentiles in the Bar Kochkba revolt. And genetically Jews in Europe are Jewish on the male line and Southern European on the female line - meaning that the Jewish males intermarried with locals. This has no impact on who is jewish or not as the entire "descended from your mother" is a later condition.

Many Jews converted, many half-Jews would spread. Over 2000 years you can expect the genes to be widely dispersed.

Irish legends and genetic markers indicate that people from northern Spain were among the first settlers of Ireland, centuries before the Celts arrived. The western Irish have a high degree of genetic markers in common with the Basques, and like the Basques have a very high proportion of Type O blood. This similarity is less evident in eastern Ireland or Scotland, where Celtic, Norman, and English ancestry are more prevalent. However, the Welsh also have similar markers showing linkage with the Basques.

The northern Spanish, notably in Galicia and Asturias, often look nothing like the Spanish stereotype. Many could pass as locals in Glasgow, Cork, or Swansea.

Until the late 19th Century, there was little, if any, Eastern European Jewish settlement in the British Isles. Most of the Jews who entered Britain or Ireland after the revocation of their expulsion under Cromwell were Sephardic or German Jews, who settled in small numbers, and then mostly in the English cities. The odds of the 17th, 18th, and 19th Century emigres from the British Isles having Jewish ancestry were very small.
