I have been able to get them open with the request feature on the profile. If this were to be automated I would add the marriage date, 130 years? Sometimes that is the only date on the profile. Another level would be having children born, say 130 years ago. If they have no dates, but the children do, this would indicate they are older. I suppose you could add parents born 200 years ago.
It is nice having people with no dates listed on the error report. A data doctor challenge would be to add at least one date (mark uncertain) if an actual date can't be found.
When trying to find if people are already on the tree, dates are really helpful.
