DNA has been very helpful in some areas of my tree, confirming my paper research and broken down one brick wall.

I did help a DNA connection to my first cousin who contacted me to trace her great great grandmother, who was a Irish brick wall, I managed to find her parents and siblings born in Ireland. She came to England in 1860 and promptly had an illegitimate daughter who was in my cousin's tree on her father's side who lied her way through all the census, birth location, marriage certificates etc. It was very satisfying, not through DNA really but only contacted me because of this woman popping up in my tree because coincidently was in my tree as a married in and my cousin as an ancestor.
