TIMELINE: https://pbase.com/daveb/med
Ancient YDNA H2 (H-FT362000). Shared by Boyt's in the US and UK. Common SNP is H-SK1180 > H-Z19049
See Also: FLR001, FLR002, FLR004, GRG022, GRG041 (Rivollat 2020), and BUCH2 (Brunel 2020)
The FLR findings of H2 are located in a rare cemetery in Fleury-sur-Orne Normandy France. See matches in France.

2020: The Boyette YDNA Surname Project BigY Y700 testing discovered 3 BigY branches in the US and two branches in the UK (Dorset). The branches in the US are closely related to each other but the branches in the UK are of a considerable distance to the common male ancestor. Based on the BigY testing the common ancestor goes back to about the year 1203. Many Medieval records from 1275 in Ireland and the 1300's and 1400's in the Isle of Purbeck, Dorset have connect the BOYT name to many important events in Ireland and England. Early professions of Archers, Royal Marblers and Reeve/Bailiff have been associated with Boyt and Boyte. Marriage records from the 1600's would indicate related families of Haviland and Cockram in and around Corfe Castle. This area was previously Saxon. More testing in the UK is needed. These Boyt lines migrated to the Virginia Colony in the mid to late 1600's creating many Boyt, Boyte, Boyett/e, Boyatt lines with the H2 YDNA.

Our answers about Irish settlers come from the skeletons of the people who lived in Ireland at one time and whose bones remain in various types of burials and tombs. In 2020, Cassidy et al sequenced another 44 individuals from Irish passage grave burials ranging in age from 4793 to 2910 BC, or about 3000 to 7000 years ago. All of the men are members of haplogroup I, except two who are a rare YDNA haplogroup H. If you only have a predicted or base haplogroup, you can certainly see if your haplogroup is upstream of any of these ancient men. However, you’ll receive the best results if you have taken the detailed Big Y-700 test, or for the mitochondrial DNA lines, the full sequence test. You can upgrade or order those tests directly from the lab.

Ancient Ireland’s Y and Mitochondrial DNA – Do You Match???

Ancient Ireland – the land of Tara and Knowth and the passage tombs of New Grange. Land of legend, romance, and perchance of King Arthur, or at least some ancient king who became Arthur in legend.
The island of Ireland, today Ireland and Northern Ireland, was a destination location, it seems, the westernmost island in the British Isles, and therefore the western shore of Europe. Anyone who sailed further west had better have weeks of food, water, and a great deal of good luck. But who settled Ireland, when, and where did they come from? How many times was Ireland settled, and did the new settlers simply mingle with those already in residence, or did they displace the original settlers? Oral history recorded in the most ancient texts speaks of waves of settlement and conquest.

According to two papers, discussed below, which analyze ancient DNA, there were two horizon events that changed life dramatically in Europe, the arrival of agriculture about 3750 BC, or about 5770 years ago, and the arrival of metallurgy about 2300 BC, or 4320 years ago. The people who lived in Ireland originally are classified as the Mesolithic people, generally referred to as hunter-gatherers. The second wave was known as Neolithic or the people who arrived as farmers. The third wave heralded the arrival of the Bronze Age when humans began to work with metals.

As reflected in the two males with H2 H-FT362000, both males are closely related but have different mothers based on the mtDNA results. The Baunogenasraid dig was just north of river Burren and close to river Aghalona: http://www.irishstones.org/place.aspx?p=594&i=9 The Jerpoint West is close to the River Nore and the Jerpoint Abby. Locations are about 50 miles apart.
