Is there a way to identify pedigree collapse?

Question

I am wondering if anyone knows of a simple way to find out where in your tree you have pedigree collapse? 

I was using the Brick Wall Ancestors app and it states that 1/554 (0.18%) are duplicates due to pedigree collapse.

I sure would like to know which Ancestor is a duplicate in my tree.

I had to look that one up: https://en.wikipedia.org/wiki/Pedigree_collapse

Answer 1

Use Ancestor Listmaker and be sure to check the box for "Show number of lines to same ancestor". If you have multiple lines of descent from the same ancestor, that ancestor's name will have the number of lines of descent in parentheses after their name. You can then click on the ancestral lines link next to their name to see all the lines.

Thank you so much! Worked great

It can also be  done by analyzing the paper trail, but it might take a bit longer.
