|Iím in a grouping- Can I tell a match from comparing TNG trees?|
Suppose you are in a DNA group that has some good matches. Suppose one of the people in your group has supplied a tree that does not meet your early ancestor and that person nor you knows exactly how you might match from a paper trail standpoint. On the tree side we always list kits together that can prove a paper trail to a given ancestor. Example, Here is group R1b-60- the kits in this group that include Reverend John Smith b c 1620 ENG match very well and are thus grouped together.
Below is the link from the tree for Kit 170423, from Thomas Smith. This kit IS listed with the matched grouping but is NOT listed with John Smith on the TREE part.
So, on the TREE side, suppose you wanted to compare Thomas Smith to see what relationship he has with John Smith. There will NOT be a relationship, because the utilty below is analyzing this from the TREE standpoint and at this point in time it is simply not known HOW that person may or may not be paper tied to John. So you can ONLY compare people with each other on the tree side who actually have a listed connection with another person.
And really, that’s the point of the DNA project, is to narrow down the field of Smith surnames to targeting research where you may match another person via DNA while not knowing the Smith tree relationship.(6/4/2014 Views 210)
For the Smith Official DNA Project (All Locations) a minimum of 25, or better, 37 YDNA markers, is strongly recommended. Many times one can appear to match other kits but the match falls apart after 12 markers. We do not attempt to match kits into groups on less than 25 with the exception of a strong paper trail or known family kinship with another tester.
