Reddit reviews Mastering Genealogical Proof

Best way is to pick a goal! I know that sounds silly but doing it helps.

The best way to start is to just concentrate on the direct line from you/the home person. That way you can just skip worrying about the 5th/6th cousins trees and just work solidly backwards. When you hit a brick wall go back to the start and start working in records that match your info and build up more detail.

Key is to actually make sure the records back up all your info - birth, death, who their parents were, marriage, etc.

Don't trust the other people's Trees on Ancestry!! Too many people just spam "add, add, add" and it's junk data. Only add trees that match with information you already know - then verify the data they add to your tree.

That way you'll have a great, and well researched tree.

I would STRONGLY recommend this book to help you get on the right track of what genealogical "proof" actually is.
