Parent Clade: I-FGC52007 emerged in a man whose father belonged to I-FGC52005, a subclade of haplogroup I1-L300, when guanine changed to adenine at position 10151343 on the man’s Y chromosome. The distribution of this man’s modern-day descendants suggests that this event occurred in Sweden about 2,200 years before present.

Project Clade: I-FGC52010 emerged in a man whose father belonged to I-FGC52007, a subclade of haplogroup I1-L300, when adenine changed to guanine at position 15832282 on the man’s Y chromosome. The distribution of this man’s modern-day descendants suggests that this event occurred in Sweden or the United Kingdom about 1,000 years before present.

Subclade: I-FGC52003 emerged in a man whose father belonged to I-FGC52010, a subclade of haplogroup I1-L300, when adenine changed to guanine at position 2867828 on the man’s Y chromosome. The distribution of this man’s modern-day descendants suggests that this event occurred in Sweden or the United Kingdom about 700 years before present.

Subclade: I-FGC52012 emerged in a man whose father belonged to I-FGC52003, a subclade of haplogroup I1-L300, when adenine changed to guanine at position 19550430 on the man’s Y chromosome. Deductions from archival research and Y-DNA testing results reveals that this event occurred in George Newman (1725-1801), who was born in Virginia about 1725.

Subclade: I-FGC52006 emerged in a man whose father belonged to I-FGC52012, a subclade of haplogroup I1-L300, when cytosine changed to thymine at position 9585192 on the man’s Y chromosome. Deductions from archival research and Y-DNA testing results reveals that this event occurred in Thomas Henry Potter (1928-2008), who was born in Oklahoma in 1928.
