Working with DNA segments on MyHeritage 

I’m watching in 2023 and this is a very good explanation

Yes the best explanation about DNA from Ran that I've heard

Thank you for a good and understandable presentation

A great explanation and I have learnt a lot. I have found a triangulated segment using my Grandmother's DNA, however I believe the DNA matches are coming through my 2x Great Grandmother's side, but she was unofficially adopted and we do not know her family. Her birth was not even recorded, so I assume she was born out of wedlock. How can I work out who her parents are just by using DNA? How can I build a tree when I do not even have a surname to search or match? Thanks

Excellent presentation. Thank you.
