The ROLL FAMILY WINDMILL, The Genealogy of the Roll Family: Jan Mangels (aka Johannes/John Roll) ******************************************** September 26, 2008 Hello, DNA Participants, I have updated the ROLL DNA Results and created new charts to accompany new results. It appears the participants with the ROLL surname have a wide variety of DNA beginnings based upon their results and the believed Haplogroup to which they belong. FamilyTree DNA site defines a Haplogroup thus: “The haplogroups are the major branches on the Y chromosome tree, defined single nucleotide polymorphisms (SNPs), which have accumulated along different lineages as Y chromosomes are passed from father to son over many generations. All haplogroups ultimately descend from a single Y chromosome carried by a male that lived in the distant past. The topology of the Y chromosome tree can be reconstructed by typing mutations in different human populations – as more SNPs are discovered (e.g., M254), the structure of the tree changes. Originally, the Y Chromosome Consortium (YCC) arbitrarily defined 18 haplogroups (A-R), which represent the major divisions of human diversity based on Y chromosome SNPs. Currently there are 20 haplogroups (A-T). In turn, each of these major haplogroups has numbered subgroups, or subclades, that are named with alternating letters and numbers.” If you have accessed your personal FT DNA website, you have seen “Y-DNA Haplotree” webpage which will tell you the above information. At this time we have participants in R, I, & J Haplogroups. So with only eight participants’ results, we learn that different groups adopted the ROLL or a variant of the ROLL surname. To validate one’s own DNA of a particular lineage it is wise also to have another (or more) branch(es) of the family of your particular line to join in the quest. As members of the human race we recognize the reality of human begetting, so we never know in our genealogy lineages if there was an adoption, an illegitimacy, and alias, or other factor which might have interrupted what we considered to be our paternal line. A distant cousin of your line should in all reality match your DNA except for the couple of mutations that may occur on the fast moving alleles/markers. http://freepages.genealogy.rootsweb.ancestry.com/~grannyapple/ROLL-RALLetc%20DNA/RESULTS.html
