Mitochondrial DNA (mtDNA) testing
A contact in Australia tells me she is descended through the mother line to Mary Jenison who married Robert Pymble. It would be interesting if there are others who have taken the test to prove a similar connection, or who may have thought to have the test.
A person's matrilineal or mothers-line ancestry can be traced using the DNA in his or her mitochondria, the mtDNA, as follows: This mtDNA is passed down by the mother unchanged, to all children. If a perfect match is found to another person's mtDNA test results one may find a common ancestor in the other relative's (matrilineal) "information table", similar to the patrilineal or Y-DNA testing.
However, because mtDNA mutations are very rare, a nearly perfect match is not as helpful as it is for the above patrilineal case -- in the matrilineal case it takes a perfect match to be very helpful.
