you never know what kind of skeletons you might find in your family tree, and what tangled roots ground it invisibly. get below the surface and all the roots are in a common darkness. ancestry said my uncle is from a different father from my dad, which i don't think is news because it's not true, but maybe. they always seemed diametrically opposed but too dramatically opposed to be from different fathers. they seemed split from the same branch, propagated by some nuclear force of mystery.
