Records that refer to more than 1 person

I see a person record:

Udo & Harald Tschira

It’s referring to 2 person. For this case, does the detail refer to Udo or Harald?

If you see any record that refer to >1 person, there is problem with this record.

All person record should be unique. No duplicates, no multiples

You can help us fix this.

Create a record for Udo Tschira and update the existing record from Udo & Harald Tschira to Harald Tschira.
