Implex is descent from a couple who are themselves descended from a common ancestor. If they are third cousins or further apart, they are not considered legally related. I entered Louis Masse as the ancestor of my second great-grandfather. Then I entered the identical data as the ancestor of his wife, my second great-grandmother. Now Geni tells me in one place that Louis Masse is my fifth great-grandfather and in the other place that he is my seventh great-grandfather (the ascending lines are unequal in years). Does Geni have any process for linking the same person's data when he appears more than once in a family tree? Is this too much for any algorithm to accomplish?
