Quoting from their DAR website
"The DAR accepts Y-DNA evidence in support of new member applications and supplemental applications. Y-DNA evidence submitted along with other documentation will be considered along with all of the other source documentation provided to prove heritage. Y-DNA will not be considered as stand-alone proof of lineage because while it can be used as a tool point to a family, it cannot be used as absolute proof for an individual."Full details of criteria can be found at the DAR website above.
