DNA testing is not a substitute for genealogical research; rather the two approaches help to corroborate each other.Genealogists compile family histories by matching up three categories of information:
I once thought of my mother's stories as history. I thought memory was history. Then I became a historian, and after many years I have come to realize that only careless historians confuse memory and history. History is the enemy of memory. The two stalk each other across the fields of the past, claiming the same terrain. History forges weapons from what memory has forgotten or suppressed. Few non-historians realize how many scraps a life leaves. These scraps do not necessarily form a story in and of themselves, but they are always calling stories into doubt, always challenging memories, always trailing off into forgotten places.The emergence of genetic genealogy has turned this two-way struggle between memory and history into a three-way battle.

Mary Anne [sic] Keane is most assuredly a daughter of Charles Keane of Baltard. I've never found anything concrete such as a baptismal record, but I have other secondary documents showing her husband Patt McInerney with a Charles Keane (could be the father or son) and now I have several DNA matches with various Blackall descendents.If this is correct, then Thomas and Tess were also fourth cousins once removed on the Blackall side.
