ancestry dna services reproduce whiteness by erasing cultural and historical specificity. the idea that you can be "40% scottish" as a material thing is horse shit. if you did genealogical ancestry and found that your great grandparents migrated from glasgow after a local industry failed, that is actually material and locates you within history.

@dankwraith Though, there are probably more dedicated services for people who've been adopted and are trying to find other ways to find relatives.

Unfortunately, there's not much for cases where parentage is in question or wasn't recorded and everyone who was there is gone. I have my doubts about DNA being all that useful even there though.
