I’m Team Italy all the way due to my residence. That said, most of my work will be on my own US family. I’ve come up with a strategy to use my “Topola Ancestors” and do a Bio Check on each of them to see what descendants they have that are marked unsourced or just suspected to be unsourced. I have about 100 Topola ancestors to work with, so it should keep me busy. So this year my “prep” has been to create a list of the Wikitree IDs for each of these ancestors and run Bio Check on each of them, listing the number of marked and suspected unsourced descendants. During the Thon I’ll start with the Ancestor with the highest number of problem children and work my way through them.
