Summary

As of January 1, 2011 The COOPER surname group has 278 participants:

· 255 have Y-DNA results.

· 51 have MtDNA results

· Addresses: 95% USA, 3% Canada, and the balance from the UK, Australia, South Africa and Chile.

· 38 lineage groups with 2 or more Y- DNA matches: 170 members or 67% of members tested.

· 85 members with no y - DNA match: it is possible that each defines a new lineage group, but this includes some 12 marker tests that may be part of an existing lineage group.

80% of the 255 y-dna tests are at 25 markers or greater, and can be used to define lineage groups

In general a 12 marker test is only included in one of the currently defined 38 lineage groups if there is a clear pedigree that has a common ancestor with others who have matched based on 25 markers or more.

Earliest Known Ancestor (EKA)

The 255 members have 97 reported Earliest Known Ancestors, and of those 72 have a date associated with the ancestor. We encourage all members to report their earliest known ancestor with an approximate date and geographic location of birth (country, state, county). This will greatly help anyone doing genealogical research

The earliest reported COOPER EKA is Richard Cooper 1538-1566 (kit # 23046) in Lineage group 23 and Haplo Group R1b1b2.

The following is the distribution of earliest dates from the 72 EKAs:

· Before 1700 7

· 1700 - 1799 30

· 1800 - 1850 27

· After 1850 8

The distribution 70 EKAs reporting by country and state is as follows with 21 from British and Ireland, 45 from USA and 4 from other countries
