Common ancestors

[Kit]

I was looking for new matches just now and found who was new and had a common ancestor. I clicked on the common ancestor button and it compares our trees.

My online tree is not complete, it has enough for people to find my more direct lines.

I noticed on the right hand side a column which I thought was just trees that had the person I was looking at on them. I was wrong. You can add the person to your tree, and you have to use on of those trees as your source.

I can just see this leading to even more errors as people will think all the trees are correct as there is a DNA match.
