The Haydock/Haddock surname project was originally established to determine if two Haydock families were related.  Both families immigrated to the United States in the 1800s (1810 and 1868) from Northern Ireland, and their oral family history suggests they initially migrated to Northern Ireland from Lancashire, England, before immigrating to the United States.  Y-DNA testing confirmed their relationship, and a kit from another Haydock residing in the United States, who can trace his ancestry back directly to Lancashire, England, appears to support the oral family history.

With the additional Haydock and Haddock men who have jointed the project, we have the opportunity to expand our investigations into other lineages. 

Y-DNA Haplogroups in the Haydock/Haddock Project

Haplogroup I originated approximately 25,000 years ago.  As the ice receded after the last glacial maximum, Haplogroup I spread into Northern Europe. It represents nearly one-fifth of Europe's male population and is the oldest major haplogroup.  The haplogroup is almost non-existent outside of Europe, suggesting that it arose in Europe.  Haplogroup I-M170 is a member of Haplogroup I and contains both Haplogroups I1 and I2.

Haplogroup I1 is the most common haplogroup I in northern Europe. It is found mainly in Scandinavia and Finland, typically representing over 35% of the Y chromosomes tested. Since I1 is associated with the Norse, it is found in all areas invaded by the ancient Germanic tribes and the Vikings. After Scandinavia, the highest frequencies of I1 are found in Germany, Austria, the Low Countries, England, and the Scottish Lowlands. I1 is between 10% and 20% of the Y DNA lineages in these areas. I-M253 is a member of Haplogroup I1.

Haplogroup I2 can be found in many of the present-day European populations, with the greatest density in Bosnia (55% & 71% in Bosnian Croats), Sardinia (39.5%), Croatia (38%), Serbia (33%), Montenegro (31%, Romania (28%), Moldova (24%), Macedonia (24%), Slovenia (22%) and Bulgaria (22%). It is also a significant percentage (between 10% and 20%) in Belarus, Hungary, Slovakia, Ukraine, Albania and the Germanic countries. I-L38,a member of the I2 Haplogroup (I2a2b), spread from central-east Germany to England via Belgium with the Celtic people of the Hallstatt and La Tène cultures between 400 BCE and 100 CE. It can be found in most of England, excluding Cornwall and Wales. I-RTF62593 and I-FTB80198 are members of Haplogroup I2.

Haplogroup R-M269 (R1b1a1b), a member of Haplogroup R1b,  is the most common European haplogroup.  It increases in frequency from east to west in Europe, with a frequency of 23.7% in Poland and increasing to over 90% in Wales. The first wave of R1b was a Proto-Italo-Celto-Germanic group that reached France by 2200 BCE, Britain by 2100 BCE, and Ireland by 2000 BCE. More than 60% of Irish and Scottish males are R1b-L21.  Due to the Viking practice of taking slaves from the native Celtic regions along the British Isles coasts, about 20% of all Icelandic male lineages are of Scottish or Irish origin.  R-L555 and R-CT3104 are members of Haplogroup R-M269.
