Those who are scouring Rosier and Rosser records looking to see how these families might be interconnected might find it interesting to also very closely scrutinize the family history notes of the ROPER family, which preceeded both the ROSIERs and ROSSERs in Virginia.
I USED to believe that these were each distinct families with some occasional confusion of records.But the more I become acquainted with the ROSIER and the ROSSER data, the more it appears to me that all three of these families in Virginia are very possibly the SAME family with some very early confusion in the spelling amongst various branches.
I would encourage ROSIERs to look closely at the ROPER family data.You may be VERY SURPRISED at what you discover!
Also, it is now possible through Y-Chromosomal DNA testing to conclusively establish whether families of a particular surname share a common male ancestor.To the extent that MALES with the Rosier / Rozier Surname can be located on both sides of the ocean who are willing to be tested, the Y-CHromosomal test can indicate pretty definitively whether two branches of a family with a common surname are actually related (though it cannot demonstrate HOW).

Dr. L. David Roper, a ROPER family historian has organized a ROPER Genetics project.It might be of interest to Rosiers and Rossers to take a look at the tentative results at the Roper family history web site:
