This is a blank form to fill in for genealogy, laboriously handcrafted by yours truly. The leftmost column is for your great-great-great-great-grandparents. There were 64 of them (give or take any cousin marriages within that span of seven generations; I've never found any, and have a reasonable expectation that the currently unknown spaces on my own tree are not duplicated in a seven-gen span).
As each of us (well, most of us) have 46 chromosomes -- 23 from each side --
at least 18 of the gggggrandparents contributed no chromosomes to my genetic constitution. That doesn't mean that they aren't my ancestors.
