    1. Re: [DNA] My Raw Data Files - Comparison 23andme vs, AncestryDNA
    2. Dave Hamm via
    3. Hello Andreas, Yep, I agree. I have compiled a massive amount of information on my surname in a three volume work, totaling nearly 1200 pages, if memory serves me. Most are the use of my surname in the U.S., but I have some records that also include England and France. Plus, I have a lot of data from my Y-DNA surname project. Most of my autosomal segments only go out to about 4th or 5th cousin. Most of the data that I have an interest in is beyond my 5th cousin. There have been more than one occasion where folks have contacted me about my male line, and I have had to say, "no, that is not my line, that belongs to this other line," etc. (because I have information on a number of branches). I have some 1900 matching autosomal segments, and some 1717 matching segments on chromosome 1, with some 1138 matching segments on chromosome 11. My tiny segment studies for my Y-DNA project group tells me that these two chromosomes are my most dense for my 'surname' in haplotype group I1-M253. So, it is standard procedure for me (when I see a large number of matches in a particular area), to look to see who else matches at that location (or, what surnames match at that location). Many times I recognize the 'other' matching segment to a surname that relates to another branch. For example, most recently a person contacted me about triangulating to one of my ancestors. I immediately saw that it was not possible to connect to the tree that I have at FTDNA, nor their tree at Ancestry. I narrowed down my search to triangulating three surnames, plus data from one of the lines in my Y-DNA project. I noticed that we matched that particular start location with two other surnames (HAM, TAYLOR, and PERRY). Several possibilities, but the location and time frame helped narrow the search on that one. (The person who contacted me did not have the correct line. We triangulate to one of my 4th or 5th cousins.) I have a large amount of data on my many 5th cousins which usually includes at least children and spouses. I am getting to the point where I have created software that can tell me what surname bunches into which segments on whatever chromosome. I am getting to the point where I can identify which branch of whatever surname matches whatever branch of my matching surname. So, when I see a large number of matches on a particular segment range then I am a very happy camper. - Dave RE: On 12/18/2015 9:20 PM, genealogy-dna-request@rootsweb.com wrote: > Date: Sat, 19 Dec 2015 08:35:35 +0700 > From: Andreas West<ahnen@awest.de> > Subject: Re: [DNA] My Raw Data Files - Comparison 23andme vs, > AncestryDNA > To: David Schroeder<dschroed991@sbcglobal.net>, > genealogy-dna@rootsweb.com > Message-ID:<E0E61E4E-8BAC-48CF-A406-929903BBEE0D@awest.de> > Content-Type: text/plain; charset=us-ascii > > We're all related to each other, so pileups are still relatives even though it might back a very long time! > > See the WAAH on CHR 2 as an example > > Andreas > >> >On 19 Dec 2015, at 02:01, David Schroeder via<genealogy-dna@rootsweb.com> wrote: >> > >> >Dave, >> > >> >"I was wondering what you were defining as a 'pile-up.'?"

    3. Would you be willing to publish this? Is it publishable? I have a publishing company, Ishi Press. I have published over 700 books.
