                                                                      Mercer DNA Project                                                                                                September 6, 2007

 
Reviewing the Patriarch page and the Mercer Group Results page should help clarify the conclusions and theories stated below.
 
Lineage I
 
          1. Conclusions: 
                 1.   The families of Thomas (b: c1655) Mary Greenaway Mercer appear to be YDNA related to the Christopher Mercer
                       b: 1612 line.
                 2.   Further research of these two lines in England might provide a patriarchal link.
                 3.   M-17 & M-16 of the Scottish Mercer line are not found to be related to the Lineage I Group but have similar point
                       of origin with the R1b1 haplotype.  
                 4.   Both Christopher Mercer and Thomas Mercer lines are found to be R1b1 and R1b1c haplotype. M-5 was the only
                       participant to be deep SNP tested with verification of the R1b1c haplotype and 4/10 are found to be the subclade
                       R1b1c. Therefore, it is likely with further deep SNP testing that Lineage I Group is R1b1c haplotype.
                 5.   Further testing was ordered for M-5 to compare to M-11 and Thomas Mercer lines.
                 6.  The Mercer name is derived from the occupation as a dealer in silks or textiles as surnames began in France
                       and England c 1100. (Wm. Camden, Remains of a Greater Worke Concerning Britaine, 1586).
                 7.  Historical accounts show William le Mercer of England c. 1200, Aleumnus Mercer witnessed a bond to Henry III in
                       1244, and Duncan Mersar of Aberdeen in 1272. Records show the Mercers of Perth Scotland were traders to
                       Holland, Normandy, and England mid 1200. Various Mercer surnames are: Mercer(English), Mercier
                       (French), Messer, and Musser (German)  www.geocities.com/wmercer.geo/home.html?200731 
                                 
            2. Theories:
                  1.  Descendants of Thomas Mercer b: c 1655 of Ayno-on-Hill,Eng M-18 from son, Joseph;  M-10, M-12, & M-14 from
                       Robert and Olive Pyle (7 generations); and M-10 & M-14 (w/1 step mutation on GATA H4 on a 37 marker test) from
                       Robert & Elizabeth Brown Mercer (6 generations). The one step mutation does not seem typical in the Thomas,
                       Jr. family line: however, further dna results of additional Robert & Eliz. family lines may show this characteristic
                       mutation.  M-20 from Robert & Olive Pyle to Job & Margaret to Job & Sarah Green Mercer line shows a one step
                       mutation on DYS 439 that mutates often.                      
                  2.  M-18 may have 2 mutations as he descends from Joseph Mercer and M-10, M-12, & M14 descend from his brother,
                       Thomas, Jr. (8 generations).
                  3.  Descendants of Christopher & Mary Mercer b: 1612 England: M-9 descends from Joseph b:1701 VA; whereas M-1,
                       M-11, & M-13 descend from his brother Thomas b:1695 VA (9 generations); M-1, M-11 & M-13 descend from
                       Christopher/Thomas/Thomas b:1672/1695/1695 respectively (7 generations); also M-1 & M-9 descend from Jacob
                       (6 generations) b:1740 ; lastly, M-11 & M13 descend from David & Elizabeth Searcy b:1791 (5 generations).
                  4.  Therefore, M-1 has 2 one-step mutations on 439/464a of 14/13 respectively on a 25 marker test, but these values
                       are known to mutate more frequently. However, M-13 has a one step mutation on DYS390 on 12 markers which is
                       not known to mutate often. Further testing of M-13 might be helpful to better understand the DYS390 mutation.
                  5.  M-17, M16, & M-6 could potentially become a Lineage II as more from this line are tested. The DYS 390 & 391 as
                       23/11 (M-17) is a subclade of historic invader/immigrant groups from Brussels, Holland, NW Germany, and
                       Denmark. www.pbase.com/image/40434624
                  6.  The R1b1c haplotype probably originated in the Ukraine or Kazakhstan 30,000 BC later migrating to Iberia
                       (Portugal & Spain) and then to Ireland. See:
                       http://en.wikipedia.org/wiki/Haplogroup_R1b_(YDNA)
                  7.  The subclade R1b1c values DYS 390/391 24/10 are found throughout Europe. DNA Map:
 
 
*As more results are completed, additional Lineages will be added.
