Do you know an easy way to find the same ancestors in different branches?

Do you know a quick and easy way to identify duplicate ancestors in your tree in the last eight (or ten) generations?

We talk about endogamy but is there a way to easily point it out for people who have broad trees going back 8 or so generations from the same geographic area?

I usually catch these on paper charts, but it would be cool if WikiTree could say A and B appear in your ancestry twice.

I also use paper charts to look for these. I find that the WikiTree Ancestors list (at is reasonably easy to skim -- and of course electronic files can be searched for other instances of a name that I think might be a repeat. I'd love to have an automated tool, but I have a hunch that this would be a major technical challenge.

Related to this, my sister recently pointed out to me that in cases of endogamy, the WikiTree Find Relationship algorithm (which is a really awesome tool) doesn't always find the shortest path to an ancestor. My example:

  1. Rachel Paine and Margaret Thayer are both great-great grand-daughters of Samuel Bass.
  2. Relationship Finder shows that Rachel is my 5G grandmother and Margaret is my 6G grandmother.
  3. But Relationship Finder shows that Samuel Bass is my 10G grandfather (tracing ancestry through Margaret Thayer) and misses the path through Rachel Paine on which he is my 9G grandfather.

Is there some way for Wiki Tree to program it in? I think it would be nice to be able to quickly access it instead of having to have it written on paper tree.

Does your program provide you with reports or lists of people?  If you list everyone alphabetically and include dates of birth and death, you could review the list to see if there are likely duplicates.  I found one person this way.
