Smith DNA Matched Group GRP-I-M253-21
for discussion of the Smith Official DNA Project group I-M253-21 that includes lineages that we believe all match together, even when the specific paper trail linkages between ancestors are unknown or cannot be proven.

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.
