| Open Rose: an Alternate Site for the ROSE Y-DNA Surname Project |
| UPDATE (21 Feb 2017): The administrator of the FamilyTreeDNA
ROSE project resigned and invited me to adopt the project. I accepted.
This alternative web site, which I opened back in 2008, then stopped updating
in 2012, will be undergoing a major over hall in the coming months.
Both this site and the official FTDNA web site will be maintained.

| Early in the history of the ROSE Y-DNA STR project, many members were
tested to only 25 markers — for the simple reason that FTDNA was only offering
25-marker STR tests. In nearly all cases, 25 markers is insufficient
to adequately support relationships. While even twelve markers may
be enough to disprove a relationship, 67 markers has become the
"sweet spot" for confidently asserting a connection and is, in some cases,
the minimum. So, my advice to anyone who initially tested fewer markers
is to immediately upgrade to at least 67 markers.
Upgrading to more markers is especially critical if you are Haplogroup R1b, the most common haplogroup in western Europe. Some 70-80% of males in the British Isles and western Europe are Hg R1b making it very easy to get a match merely by coincidence. If you are getting matches in other surnames, especially if you are getting a lot of them, you definitely need to upgrade to "shake off" these coincidental matches. Surname ROSE has many different origins, and it's a common surname in the United States — in the 1990 census, it ranked 157th in frequency out of n early 90,000 surnames. Because of this diversity and abundance, it's possible to get a low-level match with another ROSE — one as high as 25/25 — and still not be related, at least not within "genealogical time" (ca. 500 yrs or 15 generations) — we're all related if you back far enough. |
