The Roache DNA Project has had considerable success in revealing the ancestral histories of the group members.  We have identified one major ancestral branch and 5 minor lineages.  In addition, there are another 23 separate ancestral lines, each with one representative member.  Thus we now have a total of 29 separate ancestral branches for the Roche family tree.

Lineage 1
This is currently the major ancestral branch for the group and it comprises 18 members.  This represents over 30% of the project members.  The lineage dates from approximately 1100 to 1200 AD and only 2 members have a known ancestor based on traditional paper genealogy.  Therefore the common ancestors in the group would date from 1150 to 1750 AD.  The ancestral origins for the members are primarily in Ireland and the UK.  Also the location of current members include 4 countries; USA, Australia, Canada, and Ireland.  Thus the lineage has a wide migration pattern, and also one member still residing in Ireland.

The haplogroup of the lineage is E-M35 which is Mediterranean in origin.   The deep ancestry of this lineage is E-V12 (E1b1b1a1a), which originated in ancient Egypt.  Analysis of DNA databases indicate that the ancestor probably moved into Europe during the Roman /Christian era of Egypt, ~ 100 – 400 AD.  The analysis also indicates that ancestors of this lineage moved into Ireland from 1200 AD onwards.

Lineage 2
This lineage has 6 members and they descend from an ancestor who migrated to the USA in the early 1700’s.  The location of the early descendants was Orange County, North Carolina.  James Roach (born 1740, NC USA) is the most most distant ancestor for this group.  Further information on this lineage can be found on the Price & Associates website.

The haplogroup is R-P312 which is South West European.  It is most common in Iberia (35-50%) and France (20-35%), but also occurs frequently in Ireland, England and Switzerland (10-20%).  The final subgroup is R-DF83 and it appears to have an ancestral connection with England and Spain.

Lineage 3
This lineage has 6 members and the founding ancestor migrated to the USA in the early 1700’s.  The most distant ancestor is Littleberry Roach who was born in the 1750’s and lived in Orange County, North Carolina.  The predicted haplogroup is R-P312 and database matches indicate that the subgroup may be R-L226.  This subgroup is commonly referred to as Irish Type III; it is concentrated in central western Ireland and associated with the Dál gCais kindred.  Further information on this family group can be found on the Price & Associates website.

Lineage 4
This lineage has 2 members and the original country of origin is Ireland.  One member only has a 12 marker result, thus a date can not be estimated for the common ancestor.  The haplogroup is I2b1 which is predominantly found in northern Europe.

Lineage 5
This is a family group of 4 members with a known genealogical family tree.  The most distant ancestor is John Roach who was born in 1815 in Ross, Wexford, Ireland.  The haplogroup is R-L48, which is west Germanic (Frisian, Anglo-Saxon) in origin.

Lineage 6
This lineage has 2 members and the country of origin for one member is Ireland.  The haplogroup is R-M269 and database analysis indicates that this lineage probably belongs to a rare subgroup; there are almost zero matches in the entire FTDNA database.

Other Members
23 members with no common ancestor within the time period of surnames.   They represent 23 separate ancestral lines which have acquired the surname independently from other lineages.  There are at least 7 different haplogroups; R-P312, R-L21, R-U106, R-L257, I2b1, I1, and E.  This result can be expected given the nature of the surname.  It is both a geographical and habitation surname; which could be acquired by a family who lived near a rocky outcrop or crag, or by living close to a town with this name.

Summary
The Roache DNA project has currently identified a total of 29 separate ancestral lineages for the Roche family tree.

One lineage is a major ancestral branch which comprises over 30% of project members and it dates from approximately 1200 AD.
