In my Ancestry.com.au family tree there are an unknown number of Unknown relationships that should be Biological relationships.
I often spot them when I am on a profile page like below:
These are errors and I do not know how they were introduced into my tree. They are easily fixed using the Edit > Edit Relationships button to turn them to Biological but they mess up other Ancestry functionality like ThruLines.
Is there any way to search for Unknown relationships in an Ancestry tree?
I am hoping for an Ancestry.com solution, but I also have Family Tree Maker 2017.
