IN MEMORIAM: Wilmer B."Max" Maxwell, a World War II veteran and co-founder of the Maxwell-DNA project, passed away on April 5, 2014 at the age of 91 in Carlisle, PA. Read his full obituary here.

OCTOBER 2013 UPDATE: Please review the new spread sheet and the groupings for accuracy. The new spread sheet includes all donor sample kits and STR results (up to 111 markers). Email Don Maxwell M.D. [dmaxwelljr@hotmail.com] with corrections and suggestions. We plan on adding hyperlinks to each kit number (see kit 3204 on new spread sheet dated 8Oct2013 as an example). Please also send your website's URL directly to Don Maxwell M.D. Please note that the groupings on the spreadsheets (Y- DNA Test Results) are preliminary and need definitive standard primary documents proof. They represent a "probable" close family relationship but DO NOT prove a specific relationship.


The use of DNA as a genealogical tool is complementary to (not independent of) traditional genealogical research. We're all too familiar with the fact that the "paper trail" sometimes provides incomplete, conflicting information or the proverbial "brick wall" dead end. In other cases, we may suspect two disjointed lineages are connected, but we have no documentation to support the assertion. Worse yet, there can exist "proven" lines which are actually incorrect (perhaps based on faulty assumptions, misinterpretations, old records published ,online and elsewhere, without definitive proof. In all of these cases, DNA provides an unbiased method for validating (or debunking) conclusions (or theories) that are based on traditional genealogical methods. This new scientific tool is sometimes referred to as "genetic genealogy". The technology is evolving very rapidly and is now being incorporated into most current day genealogical projects.


The Y chromosome is transmitted from father to sons only. Scientists have identified a small portion of the Y chromosome which is passed virtually unchanged. Testing of this portion of the Y chromosome provides information about the direct male line, which is the father, his father, and so forth back in time. The locations tested on the Y chromosome are called "markers". Occasionally a mutation (i.e., a small change) occurs at one of the markers on the Y chromosome. These occasional mutations, are now being used as valuable new "tools" for genealogists when there is a need to identify a branch (branchlet, or twig) of a specific donor's family members. Thus, by comparing the "markers" of two individuals, we can determine if the two are related. If they are related, we can also calculate approximately how recently (% chance at certain number of generations) the common ancestor (MRCA = most recent common ancestor) lived (refered to as a TiP report by FTDNA).
