1) On First Look at my AncestryDNA Ethnicity Update - Post 2: More DNA Results (posted 13 September 2013):
a) Dan Stone offered: "While I consider this a big step forward, it will certainly continue to get even better with time and a bigger "reference collection" of people. As it stands now, the reference population they are using is still tiny. In your second graphic in this post, you will see the "reference collection" you are being compared against is only 416 people. The other ethnic categories also have similarly small numbers at this time, judging from what I saw in the updated ethnicity results of the four DNA accounts I administer.
"I have every confidence they will continue to improve their ethnicity reporting, but I'm sure many will still be complaining. Unfortunately, it seems many of those who have been complaining do not fully grasp that these ethnicity results will continue to evolve and improve, and that the ethnicity reported covers time periods way before most of our genealogy research covers."
"FTM2012 and FTM2014 allows us to handle Historical Place names correctly. I have a blog post on that. I haven't blogged about FTMM-2 but I have it, so I am not sure if FTMM-2 (current version) handles historic names yet."
"Large format printing, color and b&w, are found in most towns today. I've made several pdfs 3x5 feet. Five b&w copies ≈ $5."
