I gave my 85 year old grandmother who taught me everything I know about genealogy as a teen access to my tree….it will take me years to find and undo the damage. Ignorance of the technology can cause issues too unfortunately.This is very true. I was trying to find one or my great grandparents and I found a hint. I was about to add her but when I asked my parents it was a completely different woman.
However, one thing I forgot to mention in my prior post, the data contained on Ancestry is invaluable.
