Good news. The DAR will join SAR and the Mayflower Society who already accept DNA as an additional item of proof. Hopefully, they will include DNA lineages for others to match against as well. For details, see http://youngblog.dar.org/dna-evidence-dar-applications-and-supplementals.
I have several lines to Revolutionary War patriots that need this extra boost to qualify for supplemental memberships. We can all dust off our lineage work and see how DNA can help prove those "close but not close enough" ties.
