About us

The Roche DNA Project has been very successful - a major ancestral lineage has been identified which dates back to 1100 AD (Lineage # 1).  This lineage comprises ~ 30 to 40% of all Roche / Roach families world wide.  In addition, there are 29 other separate lineages who have acquired the surname independently from each other.  See the results sections for details.

Further material and discussion can also be found on the "Roche Lineages" website:
