Hi @Raevnn, thanks for your post! Yes you are correct. Though it will take a little more time due to processing it will save you money. Also look for sales each site offers them sporadically like around Christmas and other seasons. 23andMe used to be $300 then dropped to $99 now it’s up to $199. They may drop it down in the future but not sure. Please buy your tests through our links on DonorChildren to support our site at no cost to you! Hope you find your father, siblings, and extended family! I found my father and family through my DNA via a 3rd-4th cousin match on 23andMe. You are correct in saying you must join all three databases. Good luck!
