@ Heather; let me understand; do you want to merge them all together
Or just delete them all together at once?
If you are sure of deleting them then go ahead and do so but if they are linked in some ways to others deleting them isn't the right thing to do
I am also able to merge them together as I'm sure you probably can
Heather, the problem was that they are "no name" but they had differents mothers/fathers or children. I first unstacked all and then staccked again to do the merges. Some of them, because they had wrong parents, I must merge with Scott Hibbard's tree, because he had the same persons. This you can see here: http://www.geni.com/family-tree/index/6000000000437988097#600000000...
You're welcame! :)
PS: This only one http://www.geni.com/family-tree/index/6000000003904550281 stay because I don't know if the couple had a child. You can delete, if you know.
