GRAY/GREY Surname DNA Project
As of February 2013, we have 204 members. The tests have been analyzed and the results are shown under the Y results tab.
As expected, The Gray surname is very broad. Even for the low resolution 12 Market test where matches aren't that meaningful we have 45 unique marker strings.
We have one perfect match on a 67 marker test which means there is a 98.6% probability of a common ancestor in 8 generations and 100 percent in 20 generations.
