The testee and A share a set of grandparents (William and Mary). Mary is the daughter of Louis and Marie.<\/p>\n<p>The testee and A should have more shared matches that the testee does with B. A is more closely related. On paper:<\/p>\n<ul>\n<li>A and the testee should have 1\/2 of the same genealogical ancestry&#8211;they share two out of four grandparents, four out of eight great-grandparents, etc.&#8211;because their mothers were siblings<\/li>\n<li>B and the testee should have 1\/4 of the same genealogical ancestry.

The testee had no shared matches with A that were not also a match with B or who could not be shown to be a relative of Louis and Marie.<\/p>\n<p>Louis and Marie were ethnic French-Canadians born in upstate New York.
