Rose Family Association DNA Project
Y-Chromosome DNA Case
The Rose Family Association DNA (RFA-DNA) Project began early in the year 2002. Christine Rose, the founder of the Rose Family Association, established the project with David W. Brown as the project’s first Administrator. David was the administrator until he passed in November 2011. Timothy Rose is the current Administrator. History of RFA DNA Project
The project began as a study of the surname Rose. It has since added other similar surnames (Ross, Rosa, etc). Therefore it uses the Y-Chromosome DNA passed father to son just as our surnames do. Family Tree DNA has been the testing company since the beginning of the Rose Family Association DNA project. The Y-DNA test can be bought in increments of increasing number of markers. The more markers tested reveal more history of your Rose Y-DNA. Buy what you can afford! RFA DNA Project Background.
The results of the tests submitted to Family Tree DNA are found here: Rose - Y-DNA Classic Chart
As new tests results come in they are placed in a group of other DNA “matches”. The RFA-DNA Project began to match it’s genealogical research to specific groups of Rose families that have been verified through DNA testing to be related. The Rose Family Association (RFA) is no longer active, but for the time being the website is still active. The RFA classified 45 distinct lines of Rose families. The original RFA-DNA family groupings can be found here:
RFA DNA Project
In my own family research DNA testing was able to correct my family tree. In East Central Kentucky in the early 1800’s there were three (3) Rose families living within a radius of 30 miles. All of the previous Rose genealogists I consulted assumed that our families were all related. However, after the RFA-DNA Project was established, and enough tests came in, we discovered that none of these Rose families were related to each other through Y-DNA!
As DNA testing technology becomes more advanced, ancient DNA is being tested allowing us to look back into the ancient past. Because Y-DNA does not vary greatly over time it is being used along with mtDNA to trace family lines back to our human family origins. The Rose family that traces their lineage to Kilravock Castle has been identified. You can find them located here: RFA DNA Project (Group G)
