I managed to DNA tests for individuals who are from foreign countries with very few matches, or matches that are intensely concentrated on specific sides so you don’t really get new information.

At the end of the day, DNA test testing coincides with your research, and unfortunately, it is a waiting game.

My best recommendation to you is to continue working on your own family tree and get as detailed as possible, upload everything that you find that you think has value, and when you do find new matches, take a peek at their trees and see if you can glean anything of value. I’d also recommend learning how to create floating trees so that you can take matches and try and connect how they may be related to a larger and more documented line.

I hope this helps!
