This project was originally created for DF27+ males who not previously had any positive downstream sub clades. Since more recent SNP's discoveries have been made it possible to fine tune requirements. SNP Z31644 positive is a requirement for joining the project. If your ancestors came from either the Yorkshire England or Paris France this maybe a project for you even if your not Z31644 positive. Contact us. Brief History of the Parisi of Yorkshire England and presumed sister tribe Parisii of Gaul. History also suggests they separated from the print celtic tribe Senones. There are also archaeology digs that support a Celtic (Gaul) migration in the period of 4-500 B.C. into present day Yorkshire. The Romans identified these people in the first century as Parisi Celts and one of the Brigantes Confederation of tribes The Parisi lived in East Yorkshire. They were a small, but distinctive group of people who farmed the chalk hills of the Yorkshire Wolds. The Parisi share their name with the people who lived in France around what is today Paris although whether both tribes shared strong links is debated. The British Parisi are known for their unusual 'chariot-burials' and cemeteries. The Parisii were a Celtic Iron Age people who lived on the banks of the river Seine (in Latin, Sequana) in Gaul from the middle of the third century BC until the Roman era. With the Suessiones, the Parisii participated in the general rising of Vercingetorix against Julius Caesar in 52 BC. It is my current belief that the Parisi came to Britain in three significant waves. #1 in 400-500 B.C. #2 after the Romans defeated the Gauls about 52 B.C. #3 was an unknown number of Parisi within the host that William brought in 1066.
